    摘要: A display device is composed of a light source device and a transmissive liquid crystal display panel, and the light source device is provided with a transparent/scattering switching element capable of switching between states in which incident light is transmitted or scattered. Pixels for displaying are disposed in the form of a matrix in the transmissive liquid crystal display panel, and the need for another power supply and signals for the transparent/scattering switching element is eliminated by driving the transparent/scattering switching element using the signals and power supply for driving the pixels. The drive power source of the transparent/scattering switching element for controlling scattering can be made smaller and less costly in a display device that is capable of switching the range of viewing angles.

    摘要: 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.

    摘要: In the liquid crystal display device of the present invention, a circular polarizer is provided to each of a pair of substrates that hold a liquid crystal layer, wherein the circular polarizer on the display surface side is composed of a polarizer, λ/2 plate in which Rth>0, and a λ/4 plate in which Rth 0. Rth is a retardation in the thickness direction of a λ/2 plate or a λ/4 plate. A reduction is achieved in the absolute value of the sum of the Rth between the λ/2 plate for which Rth>0 and the λ/2 plate for which Rth 0. A circular polarizer having excellent wavelength characteristics and excellent viewing angle characteristics when viewed at an angle is thereby obtained, and a liquid crystal display device and a terminal device that use the circular polarizer are obtained.
