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： A projection optical unit for enlarged projection of an image displayed by an image display element includes a first projection optical unit having positive refractive power, and a second projection optical unit having positive refractive power for further enlarging the first enlarged image obtained by the first projection optical unit. The first projection optical unit is in an almost telecentric relationship with respect to the image display element side and the first enlarged image side, and the first enlarged image is formed at the image display element side, rather than at the second projection optical unit.

摘要： An image that has been displayed on the display screen of an image generator 1 is first passed through a projection lens section 2 consisting of a front group and a rear group. Next after being reflected on the reflecting surface of a free-form surface mirror 5, the image is further reflected by a planar reflecting mirror 4 and then obliquely projected from the lower section of a projection screen 3 onto the screen 3. The front group of the projection lens section 2 is provided for enlarging the image. In order to correct aberration due to oblique projection onto the projection screen, the rear group uses a free-form surface lens that forms a concave shape with respect to the exit side of light from the lens. The free-form surface mirror 5 corrects trapezoidal distortion due to oblique projection onto the projection screen. The free-form surface lens in the rear group of the projection lens section 2 can accommodate changes in environmental conditions by using one edge as a reference edge and rendering the other edge expandable. The free-form surface mirror can likewise use one edge as a reference edge and render the other edge expandable. For adjustment, the free-form surface mirror can also be pivoted about the reference edge.

摘要： The present invention provides a technique which can enhance contrast and brightness of a displayed image in a projection image display apparatus. According to the present invention, as a polarization splitting unit polarization-splitting incident light or exiting light upon/from a light valve, F number of a polarization splitting plane formed between prism members in an axial direction in which an incident angle of light is small (Y-axis direction) is smaller than F number in an axial direction in which an incident angle is large (X′-axis direction or Z′-axis direction) so that the light is incident so as to be tilted in the axial direction in which the incident angle is small. This can suppress an amount of change in incident angle of light upon a polarization splitting plane to a small value and can increase an amount of incident light upon the polarization splitting plane in the state that polarization-splitting performance is maintained in the best range.
