    摘要： A panel cooling system A has a pair of Sirocco fans 51A, 51B arranged at both sides of the radial direction of a projection lens 46, a suction duct portion 52A and an exhaust duct portion 52B. The suction duct portion 52A communicates a suction port of the undersurface of an armored case 2 with a suction side of each of the Sirocco fan 51A, 51B, and the exhaust duct portion 52B communicates an exhaust side of each of the Sirocco fans 51A, 51B and color lights R, G, B of an optical part. Thereby, a cooling air is blown to the vicinity of each light incident position of the color lights R, G, B of the optical part for approximately the same air quantity, so that the cooling of the optical part is performed

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.

    摘要： In a projection display provided with an optical unit, a power source unit, an external case to store the optical unit and the power source unit, a suction opening (75) is formed in one end part of the power source unit, a discharge opening (77) is formed in the other end part, and the suction opening (75) is arranged in the vicinity of an air inlet in the external case. Because the suction opening (75) and the discharge opening (77) are provided, the inside of the power source unit can be independently and efficiently cooled, and the optical unit and the power source unit can be arranged closely to each other.

    摘要： A power supply unit is formed so as to be divided into first and second power supply blocks, which are disposed on both sides of a projecting lens. This allows the power supply blocks to be efficiently disposed in a projection display device, so that dead space is not easily formed in the projection display device, making it possible to reduce the size of the projection display device. First and second power supply block cooling paths are formed at first and second power supply blocks which are liable to generate heat, respectively. A light modulating system cooling path is formed at a light modulating system disposed at substantially the center of the projection display device. Therefore, even when these component parts are closely disposed in the projection display device of a compact size, proper cooling operations can be carried out, making it possible to cool the entire projection display device more efficiently.

    摘要： A projector prevents deterioration in optical characteristics of liquid crystal panels caused by heat generated by polarizers, and sticking of dirt onto the light-outgoing surface of the liquid crystal panels. Polarizers are disposed adjacent to the light-outgoing surfaces of liquid crystal panels, while other polarizers are disposed adjacent to the light-incoming surfaces of the liquid crystal panels. The liquid crystal panels and the two polarizers disposed adjacent to the light-incoming and light-outgoing surface of their corresponding liquid crystal panels, are supported by dust protection members. The area between the light-incoming surface of each liquid crystal panel and its associated polarizer disposed adjacent to the light-incoming surface, and the area between the light-outgoing surface of each liquid crystal panel and its associated polarizer disposed adjacent to the light-outgoing surface thereof are cut off from the outside by the dust protection member associated thereto. By virtue of this structure, it is possible to prevent deterioration in the optical characteristics of each liquid crystal panel, and to prevent dirt from sticking onto the light-outgoing surface of each light valve. Therefore, a high quality image with excellent contrast can be projected.
