In one day, the electrode pitch between the liquid crystal drive electrode and the common electrode is uneven, which is arranged and combined by two or more electrode pitches. By adopting the aforementioned methods, the following functions can be achieved separately or together: · Using the aforementioned methods 1, 3, as shown in Figures 31 and 32, the daylight electrode (a part of the liquid crystal driving electrode and the common electrode) When a horizontal electric field is applied inside, the liquid crystal molecules can move in two different directions: left rotation and right rotation inside the day element electrode. As shown in the second and fourth figures, in the conventional transverse electric field method, the liquid crystal molecules can only rotate in a single direction. Therefore, depending on the direction of viewing, a color shift (c0100r shift) will occur. ) Phenomenon. In addition, if the pretilt angle of the liquid crystal is large, the viewing angle characteristics will be biased to one side, and Gu also easily generates a tone inversion in the mid-tone (right-order) field. For example, when there are two directions of left rotation and left rotation in a daylight, the aforementioned problems can all be solved. However, if the left and right rotation forces are not equalized, the liquid crystal movement in the central flexion part of the day electrode will not be uniform, and it will be printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs.

Disclmation defects. As long as the alignment defects of these liquid crystals are generated at the response speed k, people will remain at the generation site and become afterimages. The afterimages are sometimes visible to the naked eye. Also, the DisClination defective part will leak light even in black display, which obviously reduces the contrast. Using the aforementioned means 1, 3, the non-uniform daylight central and peripheral electric fields can be unified to match the rotation direction of the liquid crystal. It can completely suppress the occurrence of DiscHnatiOn defects, and prevent the application of national standards (CNS) ^ specifications (2 丨 〇 > < 297 public 544538 A7 Η 7 consumption of employees of the Central Standards Bureau of the Ministry of Economic Affairs) The cooperative prints five and thirty centimeters, and the afterimage caused by the defects of Disclination will not occur at all.

By this, the color shift (㈤or shlft), the gray level tone field inversion, and the 4 angle Problems such as characteristic bias can be solved one by one-the electric field is unified to the same direction as the liquid crystal rotation :: may-= occurrence of hschnatiQn defects', so it can completely prevent the reduction of contrast and the occurrence of afterimages. By adopting the aforementioned means i, 2, and 4 'the holding power for driving the liquid crystal can be made larger' Even if the common electrode and the liquid crystal driving electrode are located around the perimeter, the problem of holding capacitance becomes smaller can be eliminated. This can improve the aperture ratio of daylight and the efficiency of light utilization. Using the hand f 5 'can greatly reduce the chance of short circuit between the common electrode and the liquid crystal drive electrode, and significantly improve the yield. In the past, one layer was used The insulation film is separated between layers, and it is not possible to remove 7 to nothing caused by dust and the like. When using a two-layer insulation film to separate layers, the probability of defects and defects overlapping is almost non-existent. And because the insulation film becomes thicker, The dielectric breakdown voltage of the interlayer electrode also becomes relatively high, and the short-circuit phenomenon caused by static electricity will also be greatly reduced. Because the overlapping portion of the common electrode and the liquid crystal driving electrode can be freely set, the shape of the electric field distribution has been improved to the level of the liquid crystal Disclinati〇n Therefore, it is possible to prevent black light leakage and obtain a high-contrast daylight image.

The voltage of invention description (歹) can be reduced to less than half, because the image signal for low voltage (5V) drive can be used to drive 1C, which can reduce the cost of 1C . Because the driving voltage of the video signal can be reduced to less than half, the power consumption of 1C can be greatly reduced. In addition, since the amplitude of the video signal voltage becomes less than half of the conventional value, the driving force of the thin film transistor between the even field and the odd field is not easily different. Therefore, Dc bi as is not easy to appear on the liquid crystal, and it is not easy to be left. image. Due to Dot reverse drive, horizontal interference (

Crosstalk), vertical talk (Crosstalk) and flicker (Flicker) net defects will not occur. Using the above-mentioned means 6, 9, and 10, the same effect as that obtained by using the above-mentioned means 6 to 8 can be achieved. The common electrodes are separated separately, and the force and drive voltage waveforms are individually applied. The scan signal voltage waveform can be greatly enlarged. Timing degrees of freedom for voltage waveform changes. Accordingly, even if the resistance of the common electrode is increased by more than 10 times, the problem of driving Timing does not occur. As the degree of freedom of the material of the common electrode becomes wider, the film thickness of the electrode can also be made very thin, and the step difference of the common electrode becomes very small. The insulation film defect covering the step difference will not occur, and the occurrence of short circuits can be reduced. Using the aforementioned means 1 1, i 2 can achieve the same effect as using the aforementioned means 6, 9, 10. Since the common electrode does not cross the scanning signal line, the capacity of the scanning signal line becomes smaller, so the impedance value of the scanning signal line can be increased slightly. And because no cross is formed, a short circuit between the common electrode and the scanning signal line does not occur, and the yield can be improved. Using the aforementioned means 9, 1 1, and i 3, even if the common electrodes are separated from each other, it can shorten the time due to electrostatic charging, and it is not easy to produce an 11 (please read the precautions on the back before filling this page). 4 Order This paper scale applies Chinese National Standard (0 milk) 8 4 specifications (210 '乂 297 public #) 544538 Λ7 B7 V.

Using the aforementioned means 15, 16, 17 can prevent the dissolution of mobile ions containing sodium and the like in the glass substrate from penetrating out of the protective layer (custom coat), and can suppress the occurrence of the afterimage problem. In addition, since the liquid crystal can be prevented from lowering the k resistance, it can be made into a liquid-retaining panel with high charge retention and good reliability. Since it can prevent unevenness of the daytime and low contrast, a uniform and good gray scale can be obtained. It is shown that static electricity can be prevented, and dust adhesion can be reduced.

A. V. Description of the Invention When the left and right directions can be generated simultaneously in the (W) direction, it is better that the liquid crystal molecules do not contain a cyclodextrin dopant (Chlral d_nt). The main reason is that when the liquid crystal is rotated in the left and right directions, When the driving force is different, that is, the structure that is easy to occur on the electrode flexion in the fifth and seventh figures, and Dlscllnat will obviously have a low day quality in the area where the rotational driving force is weak, such as the field of D1SClination. Enlargement, you can see the reduction of contrast and afterimage phenomenon. In order to effectively solve the aforementioned problems, the buckling protrusions of the liquid crystal driving electrode (4) and the common electrode (3) are designed to overlap a small part (as shown in Figs. 6 and 8), thereby effectively preventing the occurrence of Disclimation. . For example, the seventh, eighth, tenth, twenty-sixth, and twelfth views are plan and cross-sectional views of the fourth preferred embodiment of the present invention, which reveal that the scanning signal line ⑴ and the common electrode (3) are separated by an insulating film. (4 5) A part of the structure is sandwiched between the liquid crystal driving electrodes (4). According to this structure, the holding capacity of the liquid crystal driving electrode (4) can be enlarged, so the overlapping area of the common electrode (3) and the liquid crystal horse region moving electrode (4) in the effective pixel can be reduced. Therefore, the aperture ratio of a pixel can be enlarged. In the case shown in Figure 36, the image signal wiring (2) and the common electrode (3) cross the passivation film (4 6), and the passivation film (46) is smaller than the seventh The thicknesses of the structures shown in Figures 8, 8 and 10 are even thicker: 5 to 2 times. The thickness of the passivation film, which is about 4,000 A to 600 A, is divided into two piasnm layers. The CVD device is formed, which can significantly reduce the short circuit caused by pinholes.

544538 A ΙΓ V. Description of the invention (丄 >) Structure: buckled, which can be intersected by-pixels or two pixels or more, and the ideal point (Xiza-篦 + 二 β 膂 丄) When entering the department I, the configuration is as shown in Figure 11 and Figure 15. It is also different from the common electrode (3) of the odd and even groups == ==; : = ”On the liquid crystal drive electrode (4) where the through electrodes are arranged in opposite directions, it is also necessary to apply an inverting phase to the common electrode (3 ,, knife ρ, X) ~ like L 旎 drive electrode waveform (Γ24) 'in this processing In this way, “no horizontal talk (rosstalk) will occur, and good image quality can be obtained. Applying two: waveforms that are opposite to the image signal waveform on the common electrode (3) can cause the liquid crystal to apply a large voltage signal, Compared with the common electrode used to fix the electric: rotary drive, its image signal drive amplitude can be reduced by _1 / 2 or less, so it can be manufactured with a cheap 5V drive to reduce manufacturing costs. Printing of the fourteenth and sixteenth drawings reveals a seventh preferred embodiment of the present invention The == figure, which makes the common electrode (3) across two rows and the obscure signal line (Gongya separates each and pulls out the terminal (2Q). The obscure line (1), the image signal wiring ( 2) and three separate electrodes, such as the common electrode (3), are connected to the outer periphery through antistatic non-linear elements: the antistatic connecting electrode (3 5) is connected, as shown in the figure, one to one-,---- The working waveform of the system is that the polarity of the applied voltage is changed on each independent common electrode (3) at each field period, and the liquid crystal driving electrode (4) arranged opposite to the common = pole (3) is applied in buckling.

Explanation of the invention (y) The waveform, as in the present invention, separates the common electrode (3) from each other. The conditions related to the change in the polarity of the common electrode (3) due to the application of its own inherent voltage waveform become very mild. For example, if you are hiding the signal line (扫) from ON, It is only necessary to switch the polarity of the previous scanning signal lines (), and the voltage waveform of the switch can be changed slowly. Therefore, the degree of freedom in selecting the metal material of the common electrode (3) can be greatly expanded, and the common electrode (3 The wiring resistance (resistance) problem also disappears. As shown in Figures 21 and 22, it is the most basic common electrode driving waveform. As long as the potential of the common electrode (3) is every field period If the polarity changes, it is enough to become a driving waveform. The voltage waveform from the time when the field polarity change is generated to the next field polarity change is completely free, and there is no limit on the number of cycles.

Inverse voltage signal waveforms are applied to the liquid crystal drive electrodes (4) arranged in the opposite directions to the common electrodes 4 3) of the odd and even groups, respectively, and the image signals are inverted from the common electrodes (3). Wave 幵 3, which is different from the sixth embodiment, is a driving method in which two scanning signal lines (1) are turned on at the same time. In this structure, the odd and even video signal wirings (2 The image signal voltages of different polarities are applied to), so that the day image with no interference (CrOssalk) can be displayed. Since the color configuration of the color 5 light filter can achieve delta arrangement, a day image with good color mixing can be obtained.
