摘要： A display device having an optical waveguide and a light source are provided, and also having a louver, a transparent/scattering state switching element, and a transmissive liquid crystal display panel provided in the order indicated on the side of the 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. By this configuration, abnormal flashing during switching of the radiation angle can be prevented in a planar light source device that is capable of switching the radiation angle range.

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.
