Patent ID: 8879034

Claim:
An electro-optical device comprising: a base that has a top surface and a bottom surface that is positioned opposite to the top surface; a liquid crystal layer formed over the top surface of the base; a pixel arranged in a pixel area on the base, the pixel including a capacitor electrode formed over the top surface of the base, a capacitor insulating film formed over the capacitor electrode, and a pixel electrode formed over a portion of the capacitor insulating film in plan view; an insulating film formed over a portion of the top surface of the base, the insulating film including a tilted surface that is formed along an edge portion of an opening area of the pixel arranged in the pixel area in plan view, the tilted surface sloping down from an upper layer side of the insulating film toward a lower layer side of the insulating film formed inside of the opening area; and a thin film transistor formed between the insulating film and the top surface of the base, where the thin film transistor electrically connects to the pixel electrode, wherein the pixel electrode and the capacitor insulating film are disposed over the entire tilted surface and at least a portion of the upper layer side of the insulating film, the capacitor electrode is disposed between the top surface of the base and the lower layer side of the insulating film, a refractive index of the insulating film is smaller than a refractive index of the pixel electrode, and the electro-optical device is configured such that at least a portion of a light that transmits through the liquid crystal layer is refracted by the tilted surface of the insulating film, and the portion of the light emerges out from a bottom surface of the electro-optical device.
