ABSTRACT:
The liquid crystal display apparatus of this invention includes a pair of substrates facing each other and a liquid crystal layer interposed between the pair of substrates. At least one of the pair of substrates having on a surface thereof: pixel electrodes arranged in rows and columns; a plurality of signal lines; and a plurality of nonlinear switching elements for connecting each of the plurality of signal lines to a corresponding column of pixel electrodes. Each switching element has a lower electrode, an insulating film formed on the lower electrode, and an upper electrode formed on the insulating electrode, the lower electrode being a branch of the corresponding signal line, wherein the lower electrode has a first portion with a width larger than a width of a second portion overlapping the insulating film and the upper electrode, the first portion being located farther from the corresponding signal line than the second portion.
