される。In a conventional liquid crystal display panel using MIN elements, the wiring on the substrate on the side where the elements are formed is formed of the lower metal of the MIN element and an insulating film. Here, the explanation will proceed by taking as an example tantalum as the lower metal, tantalum pentoxide as the insulating film, and chromium as the upper metal. FIG. 2 is a perspective view of a substrate on which a MIN element is formed. The wiring line 16 is a tantalum oxide film (tantalum pentoxide) 1 on the metal tantalum 11.
2 is formed. When manufacturing a liquid crystal panel, an alignment film and a liquid crystal layer are laminated on the wiring line 1G.

。その結采として生じてくる。However, in the above-mentioned technique, a direct current component is applied to the liquid crystal layer on the wiring line 16, which tends to cause deterioration of the liquid crystal and deterioration of the alignment. In addition, this DC component is tantalum, tantalum oxide film,
Because a nonlinear element is formed in the alignment film and liquid crystal layer, the ease with which current flows will differ depending on whether the tantalum side is positive and the liquid crystal layer side is negative, or when the tantalum side is negative and the liquid crystal layer side is positive. . It arises as a result of this.

Even when the L-side electrode 110 is short-circuited, no line defect occurs. If chromium 41 is not subdivided and is not lucky,
” A line defect occurs due to a short between two legs. Furthermore, even if the wiring line 1G and the pixel electrode 14 are short-circuited, image defects are less likely to occur if the chromium 41 is subdivided.
