摘要： A technique capable of increasing contrast of a projected and displayed image of a projector. A projector includes an illuminating system that emits illumination light, a liquid crystal light valve for modulating light from the illuminating system according to image information, and a projection system for projecting image light formed on a light emission surface of the liquid crystal light valve. A liquid crystal light valve includes a liquid crystal panel, first and second polarizers disposed on the side of the light incidence surface and on the side of the light emission surface of the liquid crystal panel, and first and second compensating plates disposed between the liquid crystal panel and the first and second polarizers, respectively. By using such a liquid crystal light valve, incidence angle dependency of contrast of image light formed on the light emission surface of the liquid crystal light valve is reduced, whereby it is possible to increase contrast of an image projected and displayed by the projection system.

摘要： Aspects of the invention can provide a lamp device that is capable of avoiding concentration of stresses in a sub-mirror fixing portion of an arc tube. The lamp device can include an arc tube provided with a bulb portion encapsulating inside a pair of electrodes, and a pair of sealing portions formed continuously from the bulb portion and sealing inside electrode axes having the electrodes at tip ends and conductor foils to bring the electrode axes into conduction, a main reflection mirror, to which the sealing portion is fixed, to reflect lights emitted from the arc tube toward an illuminated region, and a sub-mirror fixed to the sealing portion in such a manner that a reflection surface opposes the main reflection mirror with the bulb portion in between. The sub-mirror can be bonded with a bonding agent to a surface region of the sealing portion present in a direction moving away from the bulb portion in reference to a position corresponding to a termination of the electrode axis.

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.
