Abstract: [PROBLEM] To provide a display device capable of improving the transmittance of light at an opening that passes light while maintaining high reflectivity in a reflective layer. [RESOLUTION MEANS] Use a metal film and an reflection increasing film to configure a reflective layer provided in an element substrate to effectively utilize light of a light source. Leave a silicon nitride film that is one portion of the reflection increasing film in the opening that passes the light of the light source while removing the metal film. At this time, the film thickness of the silicon nitride film in the reflection increasing film is ¼ the wavelength of incident light and, on the other hand, the film thickness of the silicon nitride film in the opening is ½ the wavelength of the incident light. The silicon nitride film that is one portion of the reflection increasing film and a passivation film provided in a top layer of an interlayer dielectric film are laminated in the opening to achieve this structure.

Abstract: [Problem] To provide a display device with a more uniform and wider view angle not dependent upon orientation.[Resolution Means] A display device equipped with a backlight for emitting a planar light; a first aperture layer (225) whose first aperture allows light from the backlight to pass therethrough; a mechanical shutter (228) electrically driven by a thin-film transistor, that controls a transmission of light that passes through the first aperture layer; a second aperture layer (212) whose second aperture that corresponds to the first aperture in the first aperture layer allows light that passes through the mechanical shutter to pass therethrough; and a high refractive index layer (214) that covers a second aperture of the second aperture layer, that is a transparent layer with a higher refractive index than a transparent fluid (221) filling a space between the first aperture layer and the second aperture layer; a thickness of the high refractive index layer in a central portion of the second aperture is formed to be less than a thickness of the high refractive index layer at edge portions of the second aperture.
