Abstract

　射出光の水平方向の視野角が垂直方向の視野角よりも広く、かつ射出光が偏光サングラスで確認可能な垂直方向の偏光成分を有しており、さらに表示輝度を高くすることの可能な表示装置を提供する。輝度向上フィルム３３は水平方向に向けて延在すると共にその延在方向と交差する方向に配列され、さらに延在方向の屈折率が配列方向の屈折率よりも大きい複数の凸部３３ａを有している。位相差板３４は、輝度向上フィルム３３を透過した光のうち凸部３３ａの配列方向の偏光成分が当該位相差板３４を透過したのちの偏光方向と、第１偏光子２０Ａの偏光軸ａの方向とのなす角が小さくなるように、当該位相差板３４に入射した光の偏光方向を変位させるようになっている。また、第２偏光子２０Ｂは、垂直方向の偏光成分を透過する偏光軸ｂを有している。
