Abstract
There is provided a liquid crystal display device that can obtain a high light utilization efficiency and a sufficient supplementary capacitance without reducing an aperture rate of pixels and is able to attain higher resolution. A silicon nitride filmthat serves as a supplementary capacitance use transparent insulating film is formed under a pixel electrode. A common electrodethat is made of ITO and is connected to a potential common to an opposite electrode is formed under the silicon nitride film. The pixel electrode, the silicon nitride filmand the common electrodeconstitute the supplementary capacitance, and the pixel electrode, the silicon nitride filmand the common electrodeare each made to have a film thickness such that a transmittance is increased by interference at a specified wavelength.
