Abstract: A first polarizer and a second polarizer are located in an opposing relationship to each other on the optical axis of incident light with their polarization directions displaced from each other by a predetermined angle. A liquid crystal cell is arranged between the first polarizer and the second polarizer for rotation around the optical axis of the incident light. The incident light is introduced into the first polarizer while the liquid crystal cell is rotated. Transmission light, which is the incident light that has been transmitted successively through the first polarizer, the liquid crystal cell, and the second polarizer, is received by a photo-detector. The ratio between a variable component and a fixed component of the intensity of the transmission light is calculated. The cell gap of the liquid crystal cell is determined from the calculated ratio.

Abstract: A planar light source, Fresnel lens sheet, and louver are disposed in the stated order in a light source apparatus. The Fresnel lens sheet deflects and focuses in one dimension light that has entered from the planar light source. The louver is disposed in the optical path of the light emitted from the Fresnel lens sheet, and the directivity of the light can be increased by restricting the traveling direction of the light to the focal direction of the Fresnel lens sheet. The light utilization ratio can thereby be increased, the directivity of planarly emitted light can be increased, and the brightness can be made uniform at the point of observation.

Abstract: To suppress light leakage at the time of dark state, and to provide a liquid crystal display device whose electrodes in the reflection areas can be formed with high precision. The liquid crystal display device has a reflection area within a pixel unit by corresponding at least to a reflection plate forming part, and the reflection area is driven with a lateral electric field mode and normally-white. A driving electrode for forming an electric field to a liquid crystal layer of the reflection area is formed on the reflection plate via an insulating film by using a non-transparent electric conductor.

Abstract: A display device is provided including an optical waveguide, and a light source, and also a louver, a transparent/scattering state switching element, and a transmissive liquid crystal display panel, provided in order on the side of a light-emitting surface of the optical waveguide. The transparent/scattering state switching element switches between a state for scattering the incident light and a state for transmitting the light without scattering. The light source drive circuit causes the transparent/scattering state switching element to transfer from the transparent state to the scattering state, and when the viewing angle range of the display is switched from narrow to wide, the intensity of the light source is gradually increased in conjunction with the transition state of the transparent/scattering state switching element.
