Optical device and projector having the optical device
摘要：
An optical device has: a metal cooling device (500) disposed between a liquid crystal panel (441) and a light-incident side of a cross dichroic prism (443) and having a holding surface for holding polarization plates (521, 522) attached with a polarization films (521A and 522A) in a mutually spaced manner, the cooling device cooling the polarization films; a base (445) provided on the upper and lower sides of the cross dichroic prism (443) and having a cooling device attachment surface (449A) for the cooling device (500) to be attached; and a fixing member (600) provided on a light-incident side of the cross dichroic prism for locating and fixing the liquid crystal panel (441) on the light-incident side, the fixing member (600) being formed with a attachment surface (631) on which a pin (730) for mounting the liquid crystal panel (441) is formed.
摘要（中）：

光学装置具有：金属冷却装置（500），设置在液晶面板（441）与十字分色棱镜（443）的入射侧之间，并具有用于保持偏振板（521,522）的保持面 以相互间隔开的偏振膜（521A和522A），冷却装置冷却偏振膜; 设置在所述十字分色棱镜（443）的上侧和下侧并具有用于要安装的所述冷却装置（500）的冷却装置附接表面（449A）的基座（445） 以及设置在所述十字分色棱镜的光入射侧的固定构件（600），用于将所述液晶面板（441）定位并固定在所述光入射侧，所述固定构件（600）形成有附接表面（ 631），其上形成有用于安装液晶面板（441）的销（730）。
