Abstract
【解決手段】反射表示素子54の反射電極と偏光ビームスプリッタ51の偏光分離層64との間に、位相差補償素子57を設ける。位相差補償素子57の表面は反射表示素子54の反射電極と略平行に配設する。位相差補償素子57は、1/4波長板として機能する結晶位相差層86とO−plateとして機能する傾斜位相差層87とから構成される。結晶位相差層86としては、一般に用いられ安価な水晶板などの一軸性の複屈折素子を用いる。傾斜位相差層87は、主屈折率の方向が表面の法線に対して0度より大きく45度程度の容易に作製できる範囲で、かつ位相差補償素子57のヘーズを高めない程度の厚さに、無機材料など結晶位相差層86の表面に斜方蒸着することによって作製される。
