摘要： In a display device, white LEDs and bluish white LEDs are arranged in alternating fashion on the light-incident surface side of a light-guide plate. On the light-exit side of the light-guide plate is disposed a transparent/scattering switching element switchable between a state of scattering incident light, and a state of transmitting light unchanged without scattering. During a narrow-angle display, only the white LEDs are lit, and the transparent/scattering switching element is placed in the transparent state, while during a wide-angle display, both the white LEDs and the bluish white LEDs are lit, and the transparent/scattering switching element is placed in the scattering state.

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 a display panel, a plurality of pixel sections are arranged in the form of a matrix. Each of the pixel sections includes a pixel for displaying an image for the left eye and a pixel for displaying an image for the right eye. Lenticular lens having repeated convex surfaces is disposed in front of the display panel to deflect the light emitted from each pixel in the horizontal direction from the pixel for displaying the image for the left eye to the pixel for displaying the image for the right eye in each pixel section. Reflection plate reflects the exterior light toward the display panel and has surface projections on the surface. In this case, the focal distance f of the lens is different from the distance H between the surface of the reflection plate and the apex of the lens.

摘要： A light source apparatus has two or more light sources that have different light-emission spectra and that can be controlled independently, and also has light sensors for detecting the quantity of light emitted by the light sources. The light sensors are composed of one type of light sensor that is not provided with a color filter for selecting the wavelength of received light, and the light sensors are sensitive to wavelength ranges that are sufficiently broad to simultaneously receive light in red, green, and blue wavelength ranges. A control circuit controls the two or more light sources to emit light in a time sequential fashion, and compares reference data with the output values of the light sensors to control the quantity of light emitted by the light sources by means of a light source drive circuit. It is thereby possible to reduce the cost and size of a light source apparatus that is capable of correcting changes in hue.
