摘要： In a projection display device, a main board that is substantially perpendicular to a plane defined by optical axes of an optical unit is allowed to stand aside the optical unit. Therefore, if the main board is designed to have a small vertical size, the vertical size, i.e., the thickness of the projection display device, can be reduced. Therefore, unlike the conventional projection display device in which the main board is disposed above the optical unit, the entire device can be reliably reduced in thickness and size regardless of the thickness of the main board.

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 projection display device capable of improving cooling efficiency of the power unit includes a light source lamp unit, a projection lens unit, an exhaust fan provided near the light source lamp unit for ventilating an outer case, and a ventilating path provided inside the power unit. A suction fan is provided at the inlet of the ventilating path which is connected to the cooling air intake port through a duct cover to directly conduct fresh air into the ventilating path. Because the interior of the power unit is cooled by fresh air which is cooler than the air inside the outer case, cooling efficiency is enhanced.

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.

摘要翻译：电源单元被形成为被分成设置在投影透镜两侧的第一和第二电源块。这使得电源块能够有效地设置在投影显示装置中，使得在投影显示装置中不容易形成死区，从而可以减小投影显示装置的尺寸。第一和第二电源块冷却路径分别形成在易于产生热量的第一和第二电源块处。光调制系统冷却路径形成在设置在投影显示装置的大致中心的光调制系统。因此，即使这些部件紧密地配置在小型的投影型显示装置中，也能够进行适当的冷却运转，能够更有效地冷却投影显示装置整体。

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.

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
