Description
以下、図面を参照して、本発明の実施形態を詳細に説明する。
第1の実施形態では、ポンプ204を複数の液晶表示素子108、109、110に対して共通とすることで、冷却装置の小型化を達成していた。しかし、ポンプ204自体が小型化できれば、図6に示すように液晶表示素子108、109、110ごとにそれぞれ個別のポンプ204を設けてもよい。
109 赤色光用液晶表示素子(光変調素子)
110 青色光用液晶表示素子(光変調素子)
205 ラジエータ(放熱部材)
221 冷却ファン
231 緑色光用の配管
232 赤色光用配管
233 青色光用配管
301 緑色用放熱領域
302 赤色用放熱領域
303 青色用放熱領域
