First embodiment: Fig. 2 A is the display panels of the first embodiment of the present invention, and Fig. 2 B is a kind of schematic diagram of picture element array structure of the display panels of Fig. 2 A.Please refer to Fig. 2 A, display panels 200 comprises first substrate 210, second substrate 220, liquid crystal layer 230 and picture element array structure 240A.First substrate 210 comprises multi-strip scanning line 212 and many data wires 214, and second substrate 220 comprises a shared electrode 222.In addition, liquid crystal layer 230 is disposed between first substrate 210 and second substrate 220.

Please refer to Fig. 2 B, picture element array structure 240A comprises a plurality of pixel cells 250 and a plurality of protruding 260.Corresponding scanning beam 212 and data wire 214 are arranged and be electrically connected to a plurality of pixel cells 250 in the array mode, and each pixel cell 250 comprises driving component 252 and pixel electrode 254.Pixel electrode 254 has a plurality of electrode blocks, and electrically connects driving component 252.In Fig. 2 B, pixel electrode 254 for example is to have electrode block 254a and electrode block 254b.In addition, projection 260 is positioned at least one juncture area B of partial electrode block 254a and electrode block 254b substantially.In other words, projection 260 is between adjacent partial electrode block 254a and electrode block 254b.Specifically, juncture area B is meant each electrode block 254a or electrode block 254b and adjacent electrode block 254a or the zone between the electrode block 254b in the present embodiment.Further, have a juncture area B about any two or between neighbouring electrode block (254a, 254b), and also have a juncture area B between the electrode block 254a of wantonly four adjacent and rectangular distributions and the electrode block 254b.

Please also refer to Fig. 2 A and Fig. 2 B, at wantonly four adjacent and electrode block 254a of rectangular distribution and each projection 260 in the juncture area B between the electrode block 254b for example is the corner C that is adjacent to electrode block 254a, 254b, and projection 260 for example is a plurality of taper bulge-structures.Furthermore, projection 260 for example is to be disposed at data wire 214 tops and four adjacent electrode block 254a, 254b are centered around protruding 260 peripheries.In addition, the projection shown in Fig. 2 B 260 can be cone-shaped bulge structure, square taper bulge-structure, triangle taper bulge-structure or other polygonal taper bulge-structure.

According to the physical characteristic of liquid crystal molecule, under the situation that projection 260 is arranged, liquid crystal molecule can be arranged along protruding 260 edges voluntarily.Therefore, display panels 200 is subjected to single-point exert pressure after, the liquid crystal molecule of arrangement at random originally can be arranged along protruding 260 edges along with the physical characteristic of itself.In the present embodiment, by projection 260 the corner C, to influence the arrangement mode of liquid crystal molecule from each corner C corresponding to each electrode block 254a, 254b.Therefore, display panels 200 is subjected to single-point exert pressure after, the liquid crystal molecule of arrangement at random originally can recover ordered state originally fast.Say that further the configuration of projection 260 can make display panels 200 keep superior display quality.On the other hand, projection 260 is on scan line 214, and its position and non-display area are so the liquid crystal molecule around the projection 260 is if there is the indefinite phenomenon of orientation also can not influence the aperture opening ratio of viewing area.Certainly, projection 260 also can be corresponding other shading metal or light shield layer configuration, to keep the demonstration aperture opening ratio of display panels.
