Embodiment
First embodiment
Fig. 3 A is the vertical view of the multi-field vertical assigned LCD panel of first embodiment of the invention, and Fig. 3 B is the diagrammatic cross-section of the multi-field vertical assigned LCD panel of first embodiment of the invention.In order to highlight emphasis and illustrated simple and clear, Fig. 3 A has omitted illustrating of subelement, only focuses on patterning pixel electrode and the strip projected parts.Please also refer to Fig. 3 A and Fig. 3 B, multi-field vertical assigned LCD panel 200 of the present invention comprises an active component array base board 210, a colored optical filtering substrates 220 and a liquid crystal layer 230.Wherein, active component array base board 210 has a plurality of pixel cell P1.Generally speaking, pixel cell P1 is constituted by active member (not illustrating) and with patterning pixel electrode 214 that active member electrically connects.Specifically, patterning pixel electrode 214 is positioned on the substrate 212, and patterning pixel electrode 214 has a plurality of slits (slit) S1.
On the other hand, colored optical filtering substrates 220 is made of with a plurality of colored light-filtering units C1 a base material 222.Generally speaking, colored light-filtering units C1 can be red filter unit, green filter unit or blue filter unit.In detail, colored light-filtering units C1 can be by a filter membranous layer 224 and altogether with 226 formations of electrode layer (Common electrode layer).On the practice, this filter membranous layer 224 that is disposed on the base material 222 can select for use red resin, green resin or blue resins to make, to form the filter unit of different colours.By Fig. 3 B as can be known, common electrode layer 226 is positioned on the filter membranous layer 224, and can be formed with a plurality of strip projected parts (bump) 228 on the common electrode layer 226.
Here be noted that and form between common electrode layer 226 and the patterning pixel electrode 214 in order to drive the electric field of liquid crystal molecule 232.Because slit S1 228 can influence electric field with projection, so liquid crystal layer 230 can be divided out the field group (domain set) of a plurality of different alignments, so that liquid crystal molecule 232 has different toppling directions.For instance, liquid crystal molecule 232 can have four kinds of different orientations, and certainly, those skilled in the art should know that liquid crystal molecule 232 also can have more kinds of different orientations, only limits to for illustrating and being not intended at this.So, because liquid crystal molecule 232 has different toppling directions, therefore the display frame seen by different visual angles of user can both have display effect quite uniformly, and then can avoid the display frame of existing torsion nematic liquid crystal display panel 100 (as shown in Figure 1) to have the phenomenon of gray-scale inversion (gray level inversion).
It should be noted that three adjacent on the colored optical filtering substrates 220 as shown in Figure 3A colored light-filtering units C1 are be triangularly arranged (delta arrangement), it for example is in twos apart from three the shortest colored light-filtering units C1.Please refer to Fig. 4, three colored light-filtering units C1 can be red filter unit R, green filter unit G and blue filter unit B for instance, and red filter unit R, green filter unit G and blue filter unit B form with the configuration mode of interleaved.Therefore, the display frame meeting that is presented by colored optical filtering substrates 220 of the present invention is more soft.In addition, dynamic image also can have better display effect.
What deserves to be mentioned is, if generally error in the contraposition is arranged during with colored optical filtering substrates 220 at assembling active component array base board 210,228 of strip projected parts on the common electrode layer 226 can't with the slit S1 contraposition exactly on the patterning pixel electrode 214.Fig. 3 C is the projection dislocation synoptic diagram of first embodiment of the invention.In detail, the A place shown in Fig. 3 C, strip projected parts 228 ' misplaces along direction D because of the error in the contraposition.Therefore, the liquid crystal molecule that is positioned at the A place just can't effectively be controlled, thereby makes the display frame at corresponding A place may have dark line generation.
Please refer to Fig. 3 A, be noted that here it is to extend along the border of colored light-filtering units C1 that strip projected parts 228 of the present invention has an end (A place as shown in Figure 3A) at least.Because this kind layout, the bit errors of active component array base board 210 and colored optical filtering substrates 220 is under reasonable range, the bending part that strip projected parts 228 extends along colored light-filtering units C1 border can be used as the border, and then effectively control the ordered state of liquid crystal molecule, produce black line to avoid display frame.In addition, a plurality of strip projected parts 228 of the different colored light-filtering units C1 of the present invention are understood combinations with one another and similar “ Huan " font, however can not be connected each other.
On the practice, multi-field vertical assigned LCD panel 200 of the present invention also comprises a plurality of separation materials (photo spacer) 240, and separation material 240 is disposed between active component array base board 210 and the colored optical filtering substrates 220.Specifically, promote in order to make aperture opening ratio (aperture ratio), separation material 240 correspondences are disposed at the intersection of adjacent two colored light-filtering units C1, with further lifting display quality.
Second embodiment
The present embodiment and first embodiment are similar, can further promote the slit continuity strip slit on the patterning pixel electrode of present embodiment in order to make display quality.Fig. 5 is the vertical view of the multi-field vertical assigned LCD panel of second embodiment of the invention.Please refer to Fig. 5, have continuity strip slit S2 on the patterning pixel electrode 314, this helps further to reduce the probability that black line takes place in the display frame.In addition, the strip projected parts 328 of present embodiment does not painstakingly limit to its shape.The strip projected parts 328 of Y font as shown in Figure 5 only in order to explanation, and is not intended to limitation.
In sum, multi-field vertical assigned LCD panel of the present invention is because of having the advantage that leg-of-mutton colored light-filtering units and liquid crystal layer can mark off the field group of multiple orientation that is arranged in.Therefore, the image display quality of the angle of visibility of display frame and sound attitude all can effectively promote.In addition, because the bending part that strip projected parts of the present invention extends along the colored light-filtering units border can be used as the border of liquid crystal molecule, therefore the bit errors between active component array base board and the colored optical filtering substrates is under reasonable range, the bending part of strip projected parts still can effectively be controlled the arrangement of liquid crystal molecule, and then avoids display frame to produce black line.In addition, the strip projected parts of different colored light-filtering units can be connected each other.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
