Field of the Invention The present invention relates to an array substrate; and more particularly to an array substrate for a liquid crystal display that does not have a problem of a large-scale role. [Prior Art] With the advancement of technology, various electronic products have become an indispensable part of people's lives. Among them, the display is an important component of multimedia electronic products. The thin film transistor liquid crystal display (TFT LCD) has the advantages of power saving, no radiation, small volume, low power consumption, no space occupation, plane right angle, high resolution, stable picture quality, and the like. It has gradually replaced the traditional cathode ray tube display 'CRT display', which is widely used in the display panels of electronic products such as mobile phones, screens, digital TVs, and notebook computers. With the rapid development of related technologies for thin film transistor liquid crystal displays, improving the display quality has become a common goal in this field. In terms of the breadth of viewing angle, the multi-d〇main vertical alignment (MVA) technology developed by Shitong has extended the upper and lower viewing angles to 12〇. Left and right, this technology has greatly improved the viewing angle of liquid crystal displays, no less than the large viewing angle characteristics of cathode ray tubes. However, due to the application of multi-domain vertical alignment technology, there are large-scale roles and light leakage, and the process is complicated and the manufacturing cost is relatively high. The polymer is stably aligned with the defects of the multi-domain vertical alignment technology. The stabilized alignment (PSA) technology is on the rise. 201142441 The polymer design of polymer stable alignment technology makes the liquid crystal molecules have a fixed pretilt angle. When this pixel structure acts, the liquid crystal molecules will have a shorter reaction time due to the electric field between the halogen electrode and the common electrode. Deflection to the desired angle, forming multiple sub-domains with different pixel electrode shapes. However, due to the irregular distribution of the electric field, the liquid crystal molecules in the vicinity of the adjacent region of the two pixel structure are poorly arranged. The arrangement of liquid crystal molecules in the vicinity of the central region of the common line is also not ideal, as shown in Fig. 1. 1 circled area. These undesired liquid crystals cause a color washout phenomenon, which causes irregular distribution of bright areas, especially in the left and right direction. Therefore, although the polymer stable alignment technique improves the contrast, brightness, and reaction time of the thin film transistor liquid crystal display, the problem of the large-view character bias cannot be solved. In summary, the existing thin film transistor liquid crystal display has the defects of large viewing angle color shift, and the liquid crystal is arranged irregularly, which affects the bright portion and causes light leakage, which affects the display quality. Therefore, how to avoid the bias of the large-view role, improve the alignment of the liquid crystal molecules, and thus avoid light leakage is an urgent issue for the industry. SUMMARY OF THE INVENTION An object of the present invention is to provide an array substrate. The array substrate comprises a substrate and a complex pixel structure.

The first halogen electrode has an intermediate portion and a plurality of branches connected to the intermediate portion, and the first shielding layer overlaps at least the intermediate portion of the first pixel electrode 4 201142441 (overlap). Another object of the present invention is to provide an array substrate. The array substrate comprises a substrate and a plurality of halogen structures. The plurality of halogen structures are located on the substrate, and each of the halogen structures includes a first pixel electrode and a second pixel electrode. The first halogen electrode has an intermediate portion, a plurality of branches, and a first connecting portion. The plurality of branches are connected to the intermediate portion; the first connecting portion is connected to one end of at least one adjacent branch of the first pixel electrode, wherein the first connecting portion is substantially perpendicular to the intermediate portion of the first pixel electrode. The second halogen electrode is adjacent to the first halogen electrode and has an intermediate portion and a plurality of branches, and the plurality of branches are connected to the intermediate portion. It is still another object of the present invention to provide an array substrate. The array substrate includes a substrate, a first common electrode, and a plurality of halogen structures. The first common electrode is on the substrate and the plurality of halogen structures are also located on the substrate. Each of the halogen structures includes a first halogen electrode, the first halogen electrode having an intermediate portion and the -th-minute branch being vertically connected to the intermediate portion. First, the first branch of the prime electrode at least partially overlaps the first common electrode, and the first branch of the first halogen electrode has a width greater than or equal to a width of the first common electrode. With the above arrangement, the present invention can improve the color shift of a large viewing angle and thereby obtain an ideal liquid crystal alignment, thereby avoiding occurrence of light leakage, thereby obtaining better display quality. After referring to the drawings and the embodiments described hereinafter, the technical field has the usual knowledge to understand the other purposes of the present invention, and the technical means and embodiments of the present invention. The above described features and advantages of the present invention will become more apparent from the description of the appended claims.
