Embodiment approach 1
[0052]
[0053] First, as the electro-optical device of the present invention, a liquid crystal device using liquid crystal as the electro-optical material will be described as an example. The liquid crystal device has a liquid crystal panel AA as the main part. The liquid crystal panel AA is a thin film transistor (Thin Film Transistor: hereinafter referred to as "TFT") as the switching element of the element substrate and the counter substrate facing each other with the electrodes formed facing each other and keeping a certain distance between them. Liquid crystal is clamped in the middle.
[0054] Hereinafter, the overall structure of the liquid crystal panel AA will be described with reference to FIGS. 1 and 2. Here, FIG. 1 is a perspective view showing the configuration of the liquid crystal panel AA, and FIG. 2 is a cross-sectional view taken along line Z-Z' of FIG. 1.
[0055] As shown in these drawings, the structure of the liquid crystal panel AA is that the glass and se...
Embodiment approach 2
[0079] Next, the liquid crystal panel AA of the second embodiment will be described. This liquid crystal panel AA has the same structure as the liquid crystal panel AA of the first embodiment except for the arrangement of the protrusion pattern 10.
[0080] Fig. 9 is a plan view showing a detailed structure of the liquid crystal panel of the second embodiment. FIG. 10 is a schematic plan view showing the relationship among protrusion patterns, data lines, scanning lines, and light shielding layers of the same panel. As shown in these drawings, the protrusion pattern 10 is formed so that a part of it overlaps the scanning line 2. As described above, since the formation of the first light shielding layer 71 covers the scanning line 2, if a part of the protrusion pattern 10 is arranged to overlap the scanning line 2, the second light shielding layer 72 and the first light shielding layer 71 are in the area 73 overlapping. In other words, when a part or all of the protrusion pattern 1...
Embodiment approach 3
[0083] Next, the liquid crystal panel AA of Embodiment 3 will be described. This liquid crystal panel AA has the same structure as the liquid crystal panel AA of the first embodiment except for the arrangement of the protrusion pattern 10.
[0084] FIG. 12 is a plan view showing a detailed structure of a liquid crystal panel of Embodiment 3. FIG. As shown in this figure, the protrusion pattern 10 is formed so that a part of it overlaps the capacitor line 4. Generally, the flatness of the insulating film formed on the element substrate 151 is greatly dependent on the various patterns located below it. Therefore, if there are a plurality of patterns under the insulating film where the protrusion patterns 10 are arranged, the thickness of the insulating film is likely to be uneven in the given area. However, since the capacitor wire 4 has a thick line width and excellent flatness, the thickness and flatness of the insulating film on the upper portion thereof are good. Then, a part of...
