摘要： A projection optical unit for a projection display apparatus, which displays an image upon a projection surface, obliquely, includes a front lens group disposed in a direction from an image display element to a projection surface, a rear lens group, and a reflection mirror formed so that a curvature of a portion for reflecting a light beam incident upon a lower end portion of the projection surface is larger than a curvature of a portion for reflecting a light beam incident upon an upper end of the projection surface. An optical axis of the front lens group and the rear lens group is more inclined with respect to a direction of the portion of the reflection mirror for reflecting the light beam incident upon the lower end portion of the projection surface than a normal line direction of the image display element.

摘要： A technique for a display device using a display panel with Lambert light distribution, such as a plasma display panel, which displays a bright image with less contrast deterioration. This device has a front sheet which is integrally or separately located in front of the display panel. The front sheet includes light guides which extend in the horizontal direction and have a virtually convex cross section in the vertical direction with their apexes on the light exit side. A light reflection layer and a light-absorbing layer are sequentially stacked on the lateral sides of the light guides.

摘要： In a projection type image display apparatus, for enlarging an image on a image display apparatus 1 by means of a projection lens 2, thereby projecting the enlarged image onto a screen 6, obliquely, being inclined thereto, between the projection lens 2 and a rear-surface mirror 5, there are disposed free shaped surface mirrors 3 and 4, each having a free shaped surface for compensating a trapezoidal distortion due to oblique projection of the enlarged image. The surface configuration of the free shaped surface mirror is so shaped as to satisfy a following equation: |L1−L2|>1.4·Dv if assuming that a distance for a light beam of an upper end of the enlarged image to reach the screen after being reflected upon a free shaped surface is “L1”, a distance for a light beam of a lower end of the enlarged image to reach the screen after being reflected upon the free shaped surface is “L2”, and a distance from an upper end of an image on the screen to a lower end thereof is “Dv”.

摘要： A polarization splitting section has a structure in that a polarization splitting layer is formed of a light reflecting grid member which is arranged in a grid-shaped pattern on an optically-transparent substrate, and an optically-transparent medium is filled between the grid member and the substrate in contact with the grid member surface and the substrate surface, and the grid member and the filled optically-transparent medium are bonded to the substrate with another adhesive agent or tackiness agent formed of an optically-transparent medium interposed. The polarization splitting layer is partly protruded externally from the surfaces of prism materials.

摘要： For enabling to prevent ill effects from being generated in the structures of a reflection mirror, even if increasing an output energy from a light source, thereby preventing ill influences from being exerted on the driving condition thereof, a mirror drive controller unit 7 reads out history data of the past, relating to temperature changes on a micro mirror 1, from a first LUT holder unit 19. Upon basis of the read-out history data of the past is presumed the temperature on the micro mirror 1 at the present time. The presumed temperature on the micro mirror 1 is temperature P temp of the micro mirror 1 at the present time, and upon that P temp are changed vibration (or oscillation) condition of the micro mirror 1 in the horizontal (H) direction and vibration (or oscillation) condition thereof in the vertical (V) direction.
