摘要： A display apparatus displaying an image includes a light source, a light valve, a light cross-section converter and a light scanning mechanism. The light valve has a screen formed of a plurality of pixels. The light cross-section converter converts light emitted from the light source into illumination light having a cross section enough to illuminate at least one pixel at a time. The light scanning mechanism controls a direction of travel of the illumination light in such a way that the illumination light scans the plurality of pixels. The light scanning mechanism controls at least one of sequence, speed, and number of times of scanning where the illumination light scans the plurality of pixels, so that a desired profile of distribution of illuminance is obtained over an entire surface of the screen for a time period not longer than one frame time of an image.

摘要： A plurality of reflecting mirrors (322) extending in the vertical direction of a screen are provided in parallel as appropriate between a light incident surface and a light exiting surface. The reflecting mirrors (322) each have a shape of parabolic cylinder, for condensing light on substantially one line. Light rays (L2) are reflected from a concave mirror part on the inner surface of one of the reflecting mirrors (322), and are reflected again from a convex mirror part of an adjacent one of the reflecting mirrors (322), to be emitted to the outside. Being reflected from the inner surface of one of the reflecting mirrors (322), the light rays (L2) are condensed on a predetermined focal point (FP1), and are then emitted while diffusing. Thus obtained is a diffuser panel for a rear projection screen capable of contributing to improved clarity of images.
