Liquid crystal projection color display apparatus. |
摘要 |
<p>In a liquid crystal projection color display apparatus having three liquid crystal display devices used for red, green and blue lights, each liquid crystal display device has a liquid crystal display panel and a microlens array disposed on the light-source side or the light-source and screen sides of the liquid crystal display panel. The microlens array has a controllable refractive power by applying an electric power. An electric voltage is applied between transparent electrodes formed on both surfaces of a microlens array so that the refractive power of the microlens array can be made a value adapted to suit the corresponding one of red, green and blue lights. <IMAGE></p> |
