    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: Light emitted from a light source and incident on a light distributor of a light guide plate is partially emitted from the light guide plate as it is, and is predominantly reflected toward a prism section. Light incident on the prism section from the light distributor and light incident on the prism section directly from the light source are refracted and reflected by the prism section, and are then emitted from a light emission plane of the light guide plate in a region away from the light source in which the light distributor is not disposed, in a direction perpendicular to the light emission plane and substantially away from light source.

    摘要: In an LCD projector, a color mixing optical system for mixing color beams transmitted through LCD elements includes an optical path length adjuster in three light paths from a light source to the LCD elements. The adjuster includes polarization beam splitters, phase plates, and light-beam reflectors. The numbers of reflections of the color beams in the optical paths from the light source to the projection lens are set only to odd values or only to even values. The adjusters are arranged and configured to equalize the respective optical path lengths to each other. With this configuration, the relative distribution of intensity of illumination is substantially equalized for the beams illuminating the respective LCD elements. Compounding the beams, there is attained a projected screen image with a satisfactory white balance and homogeneous chromaticity and luminance. Consequently, there is implemented an LCD projector capable of projecting on a screen an image having a favorable white balance and uniform chromaticity and luminance.
