Problems solved by technology

The problem that exists here is, when using methods such as sputtering to form ITO film on glass substrate 81, if Figure 7 As shown, the part of the ITO film 88' that overlaps the second electrode 86 of the MIM element cannot be completely adhered to the second electrode 86, and there is a problem of forming a gap G between the two.
Moreover, if it is a qualified product, it will be marketed as a finished product, and if it is a non-conforming product, it will be discarded
However, because the transparent pixel electrode formed on the element substrate side is almost colorless and transparent, it is necessary to correct it in a short time in the existing liquid crystal device made by visually inspecting it as a reference. It is very difficult to check

Abstract

A liquid crystal device comprises a plurality of pixel electrodes (6), and nonlinear elements (11) including element-side electrodes (14) electrically connected to the pixel electrodes (6). An element-side electrode (14) is shaped in a pattern (14a) formed along the edge of a pixel electrode (6). The presence of the element-side electrode pattern (14a) makes it possible to prevent etchant from entering between said pixel electrode (6) and the element-side electrode (14) and causing a wire break therebetween in patterning the pixel electrode (6). When the element-side electrode pattern (14a) is made of a substance having a higher light-shielding ability than that of the pixel electrode (6), it may be used as a mark for adjusting position in bonding an element substrate and an opposite substrate.
