Abstract
A two-terminal nonlinear element for a liquid crystal display device, which is connected to a corresponding one of pixel electrodes of the liquid crystal display device, includes: a lower electrode connected to a signal line formed on one substrate of the liquid crystal display device; an insulating film formed on a surface of the lower electrode; and an upper electrode formed to face the lower electrode via the insulating film and connected to the corresponding one of the pixel electrodes. The insulating film has a first portion interposed between the upper electrode and the lower electrode and a second portion surrounding the upper electrode and having a thickness larger than that of the first portion, and the first and second portions of the insulating film are made of a same metal oxide produced by anodization.
