Embodiment approach 1
[0062] (Outline of Liquid Crystal Display Element 10 )
[0063] while referring to figure 1 and figure 2 , the liquid crystal display element 10 according to one embodiment of the present invention will be described. figure 1 (a) is a top view showing the outline of the liquid crystal display element 10 , figure 1 (b) is shown figure 1 (a) A schematic cross-sectional view of a cross-section along line A-A shown. figure 2 (a) is to figure 1 Part of (b) enlarged view, figure 2 (b) is with figure 1 (a) An enlarged view of the cross-section of the line A-A parallel to the scan line 20 on the line. figure 2 (c) with figure 2 (a) likewise would figure 1 The partially enlarged view of (b) shows a state where the backlight 29 is incident on the liquid crystal layer 13 .
[0064] The liquid crystal display element 10 is a VA mode liquid crystal display element which is one of vertical electric field type liquid crystal display elements, and uses dot inversion driv...
Embodiment approach 2
[0130] (liquid crystal display element 50)
[0131] while referring to image 3 , a liquid crystal display element 50 as another embodiment of the present invention will be described. image 3 It is a plan view showing the outline of the liquid crystal display element 50 . The liquid crystal display element 50 differs from the liquid crystal display element 10 in the shapes of the common electrode 51 and the TFT 53 . Therefore, in this embodiment, the common electrode 51 and the TFT 53 will be described. In addition, the same components as those included in the liquid crystal display device 10 are denoted by the same reference numerals, and description thereof will be omitted.
[0132] (common electrode 51)
[0133] The liquid crystal display element 50 is a VA mode liquid crystal display element similarly to the liquid crystal display element 10 . However, the liquid crystal display element 10 is driven by dot inversion driving, and the liquid crystal display element 50 ...
Embodiment approach 3
[0145] while referring to Figure 4 , the liquid crystal display element 60 which is still another embodiment of the present invention will be described. The common electrode 61 included in the liquid crystal display device 60 has a different opening shape than the common electrode 51 included in the liquid crystal display device 50 . The shape of the common electrode 51 is a rectangle. Therefore, when the length of the common electrode 51 in the direction parallel to the signal line is defined as the width, the width is always constant.
[0146]However, the width of the common electrode 61 is not fixed. The width of the common electrode 61 in the area where the signal line 19 is provided and the peripheral area where the signal line 19 is provided is formed larger than the width of the common electrode 61 in the area other than this area.
[0147] Thus, the common electrode 61 can cover a relatively large area in the area where the signal line 19 is provided. Therefore, i...
