、緑、青の3原色光に分離し、これらの3原色光
を反射ミラーによりダイクロイツクプリズムの側
面に対向して配置された3枚の液晶表示パネルに
それぞれ入射させ、各液晶表示パネルを透過した
3原色光を上記ダイロクロイツクプリズムの光出
射面から出射させ、このダイクロイツクプリズム
から出射した3原色光を投影レンズにより拡大し
てスクリーンに投影する液晶表示装置において、
前記ダイクロイツクミラーおよび反射ミラーを、
前記光源から各液晶表示パネルまでの光路長が等
しくなるように三次元的に配置したことを特徴と
する液晶表示装置。 The light from the light source is separated into the three primary color lights of red, green, and blue by a dichroic mirror, and these three primary color lights are sent to three liquid crystal display panels placed facing the sides of the dichroic prism by a reflecting mirror. A liquid crystal display system that causes the three primary color lights that are incident on each liquid crystal display panel to be emitted from the light output surface of the dichroic prism, and that the three primary color lights that have been output from the dichroic prism are magnified by a projection lens and projected onto a screen. In the display device,
The dichroic mirror and the reflective mirror,
A liquid crystal display device characterized in that the light source is three-dimensionally arranged so that the optical path length from the light source to each liquid crystal display panel is equal.
