Problems solved by technology

[0007] However, if the rubbing process is performed with the configuration shown in FIG. 7(a) and FIG. 7(b), there is a problem that, inside the gap portion 9b of the common electrode 9a, the progress of the rubbing roller relative to the common electrode 9a On the direction side, the frictional defect 16a occurs in a wide range due to a large step difference in the thickness of the common electrode 9a, and such a frictional defect 16a causes a decrease in the quality of a displayed image such as a decrease in contrast.
However, if the film thickness of the common electrode 9a and the pixel electrode 7a is thinned, the resistance of the common electrode 9a increases, and this increase in resistance becomes a cause of occurrence of luminance unevenness in an image, etc.
[0008] In addition to the aforementioned rubbing defect, if the thickness of the common electrode 9a is thick, poor alignment may also occur due to the level difference itself, or may be caused by the gap between the region where the common electrode 9a is formed in the pixel and the slit-shaped gap portion 9b. Changes in the thickness of the liquid crystal layer may also reduce the contrast of the display

Abstract

The invention relates to a liquid crystal device, a manufacturing method of the liquid crystal device, and an electric device. The invention provides a liquid crystal device capable of inhibiting FFS mode of occurrence of friction disorder without increasing resistance of an electrode layer. On an element substrate (10) of the liquid crystal device (100), an upper layer side of a film transistor (30) is covered by an interlayer insulated film (6) made from an organic flattened film; on the upper layer of the interlayer insulated film (6), a common electrode (9a) is formed as an electrode layer of the whole surface. An inter-electrode insulated film (8) forms on the upper layer of the shared electrode (9a). A pixel electrode (7a) with a gap part (7b) with seam shaped forms on the inter-electrode insulated film (8). Compared to the common electrode (9a) on the whole surface, the pixel electrode (7a) with the gap part (7b) of seam shape has thin film thickness, so that the pixel electrode (7a) is capable of undergoing friction treatment appropriately.
