摘要： A liquid crystal projector device of the present invention includes a lamp unit, an optical system for separating light emitted from the lamp unit into light of three primary colors, and an image synthesizer for generating image light of three primary colors from the light of three primary colors, and synthesizing the generated image light of three primary colors into color image light. The image synthesizer includes three liquid crystal panels for three primary colors and three incidence polarizing plates arranged at light incidence sides of the liquid crystal panels. Each of the incidence polarizing plates includes a glass base material and a polarizing film joined to a surface thereof. The surface area ratio of the glass base material to the polarizing film is set to 178%.

摘要： A projector apparatus equipped with a metal plate structure serving as a light shield against a light source and as a heat radiator is provided. The metal plate structure is arranged over the light source to hide the light source. The metal plate structure extends farther to a cooling fan and connects to the upper end of the air expiration face of the fan. The metal plate structure thus serves as the top plate of the baffle section of the exhaust duct of the fan for leading the air expired from the fan. The metal plate structure also serves as a shield plate, which can be connected to a grounded metal piece.

摘要： A duct was configured such that an incident side and an outgoing side of each of liquid crystal panels 34r, 34g, and 34b are formed with discharge ports r1 and r2, g1 and g2, and b1 and b2 to discharge the air from fans 41 to 43 through ducts 411 to 431, and at the same time, a PBS 28 for aligning the polarizing direction of the light from a light source lamp is formed with a discharge port p1 to discharge the air from the fan 43 through the duct 432, and an incident side discharge port b1 and an outgoing side discharge port b2 of the liquid crystal panel 34b corresponding to the blue light are formed with the ducts so as to discharge the air from the fans 43 and 41 which are different from each other. As a result, even when an amount of light per unit area of high luminance is increased, the liquid crystal panels and the polarizing plates and the PBS can be effectively cooled by three sets of the fans.
