摘要： The invention provides a technique for reducing unevenness in brightness and color of images to be displayed in a projector. A projector includes an illumination system for emitting illumination light, an electro-optical device for modulating light from the illumination system according to image information, and a projection system for projecting a modulated light beam obtained by the electro-optical device. The electro-optical device has a polarizer 302Bo on at least one of the light incident side and the light emergent side, and the polarizer is stuck on a flexible and transmissive plate material 308 that bends in response to changes in shape of the polarizer. This makes it possible to reduce unevenness in brightness and color of images to be projected and displayed.

摘要： A light source device (120) of the present invention includes a light source lamp (122) and a reflector (124) that reflects light emitted from the light source lamp (122). The reflector (124) is formed of a ceramic having a thermal conductivity of at least about 2W/m·K (0.005 cal/cm·s·°G) at a temperature of 20°C. This arrangement of the light source device (120) effectively lowers the ambient temperature of the light source lamp (122).

摘要： A discharge-lamp lighting apparatus includes a control circuit that determines electric power supplied to a high-pressure discharge lamp after the high-pressure discharge lamp is started by an igniter. The electric power is determined in accordance with a voltage corresponding to a lamp voltage detected by a voltage detection circuit and a drive current detected by a current detection circuit. When the determined electric power is less than predetermined electric power, the control circuit causes a down chopper to control the drive current such that an amount of increase in the electric power per unit time becomes equal to or less than a predetermined value.
