摘要： A liquid crystal display element, which is installed in a projection-type color liquid crystal display, is provided with the first glass substrate. The first glass substrate is provided with the first micro-lens array on its light-incident side and the second micro-lens array on its light-releasing side. The first micro-lens array converges light beams of respective primary colors onto the vicinity of the light-releasing position on the second micro-lens array. The second micro-lens array makes the incident light beams parallel to each other and releases them from the liquid crystal display element. Thus, even in the case of using a projection lens having a small diameter, it is possible to improve the efficiency of utilization of light. Moreover, this arrangement eliminates the necessity of having to employ a comparatively expensive projection lens with a large diameter, thereby reducing the costs of production.
摘要翻译：安装在投射型彩色液晶显示器中的液晶显示元件设置有第一玻璃基板。第一玻璃基板在其光入射侧设置有第一微透镜阵列，在其光释放侧设置有第二微透镜阵列。第一微透镜阵列将各原色光束会聚在第二微透镜阵列上的光释放位置附近。第二微透镜阵列使入射光束彼此平行并将它们从液晶显示元件释放。因此，即使在使用具有小直径的投影透镜的情况下，也可以提高光的利用效率。此外，这种布置消除了必须使用具有大直径的相对昂贵的投影透镜，从而降低了生产成本。

摘要： The present invention provides a lighting device including a light source; a reflecting mirror for reflecting light emitted by the light source in a determined direction; and a compensating element for receiving the light from the reflecting mirror and allowing the light to outgo in the form of parallel rays. Further, a projection type image display system including the above-mentioned lighting device and a display element for forming an image by receiving light from the lighting device is provided. According to the present invention, light can be emitted with a satisfactory degree of parallelization and an even illuminance, constant irregularity due to the photoelasticity can be degraded, and the degradation in brightness of a projected image due to a low ratio of aperture can be avoided. Thus, a uniform image with no illuminance irregularity can be projected.

摘要： A light source device emits light for positional alignment and light for adhesion toward the optical devices. A position detecting device receives the light for positional alignment from the optical devices and optically detects a positional displacement of the optical devices. A positional alignment mechanism moves the optical devices with respect to each other in accordance with a detecting result of the position detecting device, thereby positionally aligning the optical devices. After the optical devices are positionally aligned, the light for adhesion is radiated to a photo-curing adhesive resin interposed between the optical devices, thereby adhering the optical devices.
