Embodiment approach
[0051] Specifically, since the projected area of the compensation electrode 423 on the bottom plate 10 is not larger than the projected area of the second common electrode 422b on the bottom plate 10, the storage capacitance of the pixel electrode 421 in the sub-region is reduced. In order to further reduce the V ft To balance the common voltage between the main region 41 and the sub-region 42 , it is necessary to increase the overlapping area between the pixel electrode 421 of the sub-region and the common electrode 422 of the sub-region. There are two implementation methods here. The first one is to increase the width of the first common electrode 422a along the extending direction of the scanning line 20, that is, to increase the distance between the light-shielding area of the sub-region pixel electrode 421 and the first common electrode 422a. The overlapping area between them; the second one is to increase the width of the second common electrode 422b along the exten...
