Abstract
【解決手段】 液晶表示装置1では、アレイ基板11は、アレイ基板11の前面から与えられる光を検出する光センサ1112を備え、対向基板13は、光源14からの光が透過するカラーフィルタ132と、カラーフィルタ132を透過した光が透過し且つ複数の画素電極113に対向する透明な透明電極134aと、他の複数の画素電極113に対向し且つ外光を反射する反射電極135を備える。検出対象である光は直接的に光センサ1112に与えられるので光を精度良く検出できる。また、光源14からの光が透明電極134aを透過するとともに外光が反射電極135で反射するので、透過表示と反射表示が可能になる。
【選択図】図1
