Abstract
A liquid crystal display device with excellent display characteristics such as dot defects and missing of pixels prevented from occurring, a bright display screen and the like can be realized. In addition, a yield rate is enhanced remarkably. The display device has a transparent substrate, non-linear elements, each having a plurality of electrodes, disposed on the transparent substrate, a protective film disposed on each respective nonlinear element of above, an interlayer insulating film disposed on the protective film and a pixel electrode disposed on the interlayer insulating film. An opening, the cross-section of which is configured in a V-letter like slanting shape, is formed in the protective film and interlayer insulating film, respectively. The opening is exposed to the surface of the nonlinear element. Each respective opening of above forms a first end part on the protective film and a second end part on the interlayer insulating film and the first end part is located outside of the second end part. One of the plurality of electrodes disposed on the nonlinear element is in contact with the pixel electrode in the opening.
