    摘要: A projector for separating white light into three primary colors, forming images with liquid crystal light valves, mixing these images, and projecting an enlarged picture of the mixed images with a projection lens. The projector includes an optical unit having a light source, a plurality of dichroic mirrors for separating the white light into blue, green, and red beams, respective liquid crystal light valves forming images of the blue, green, and red colors. The optical unit has a chassis with a rigid center portion at which one of the liquid crystal light valves is mounted, the other two light valves being mounted symmetrically with respect thereto. An adjustment mechanism is provided for matching pixels of the second and third color valves with those of the first color valve. The red color liquid crystal light valve is disposed midway between the blue and green color liquid crystal light valves and a cooling fan is disposed below the red color liquid crystal light valve.

    摘要: Liquid crystal modulation elements are arranged so that light outgoing surfaces thereof face light incident surfaces of a color synthesizing prism. Transparent plates are bonded to the light outgoing surfaces of the liquid crystal modulation elements. For this reason, adhesion of dust to the light outgoing surfaces of the liquid crystal modulation elements can be prevented. Further, it is possible to prevent light reflection at the interface surface between the light outgoing surfaces and air due to the difference in refractive index therebetween. This allows a high-quality image to be projected without deteriorating the switching characteristic of the liquid crystal modulation elements while preventing dust from adhering to the light outgoing surfaces of the liquid crystal modulation elements.

To this end, a projection display according to the present invention preferably includes a color synthesizer for combining colored and modulated light beams, comprising: a square column dichroic prism composed of four triangle prisms having equal refractive index together whose cross sections are right isosceles triangles such that three light valves are located adjacent to three exterior peripheral surfaces of dichroic prism to receive colored and modulated light beams therefrom and; a filter for absorbing light with a specified wavelength range, leaked from surface of dichroic prism at the opposite side of incident light surface and directed to liquid crystal light valve, the filter being located between liquid crystal light valves and surface of dichroic prism. As for construction of the dichroic prism itself, specifically, of the four aforementioned triangular prisms, the first triangular prism and the aforementioned third triangular prism are mutually affixed in a condition in which there is a first step difference in the vertical direction. The first exposed side is formed on one edge of the affixed side of the first triangular prism. Similarly, the second triangular prism and the fourth triangular prism are attached to each other such that there is a second step difference on the same edge, and a second exposed side is formed on one edge of the affixed surface of the second triangular prism. Further, the first and the third triangular prisms and the second and the fourth triangular prisms are attached, with a step difference between them, in such a way that the aforementioned first exposed side and the aforementioned second exposed side are located on the edges facing the same direction; and a third exposed surface that is orthogonal to the aforementioned first and second exposed surfaces is formed between the aforementioned first triangular prism and the aforementioned second triangular prism.
