Abstract

　高輝度・薄型で光の利用効率が高い低消費電力の液晶表示装置を提供する。 　液晶表示装置１０は、液晶表示パネル１１と、液晶表示パネル１１のＲ、Ｇ、Ｂ画素３３Ｒ、３３Ｇ、３３Ｂで構成されるＲＧＢ画素３３の配置に対応して設けたレンズアレイ２６と、レンズアレイ２６のそれぞれのレンズ３４に対して一定で、かつ色ごとに異なる入射角度で入射させる面状照明装置１５と、を備えている。この面状照明装置１５はＲ、Ｇ、Ｂ光１２、１３、１４を出射するレーザ光源と、Ｒ、Ｇ、Ｂ光１２、１３、１４を一方の主面２３からそれぞれ異なる出射角度で出射する導光板２４を含んでいる。そして、導光板２４から出射するＲ、Ｇ、Ｂ光１２、１３、１４は、レンズ３４により集光されて対応する各画素に対して、それぞれＲ、Ｇ、Ｂ光１２、１３、１４の光量が増加して入射する。
