Abstract
When axes are projected to a reference surface perpendicular in the thickness direction of a liquid crystal layer, a rotational angle φof an alignment axis of a liquid crystal layer from a reference direction on the reference surface, a rotational angle φof a transmission axis of an incident-side polarizing plate from the reference direction, a rotational angle φof a transmission axis of a wire grid element from the reference direction, and a rotational angle φof a transmission axis of an exit-side polarizing plate from the reference direction satisfy all the equations below:44°≦φ-φ<45° or 45°<φ-φ≦45°1≦φ2, where1=0.191×φ+0.986×φ−14.435 and2=0.191×φ+0.986×φ+14.435, and1≦φ−90°≦2, where1=0.064×φ+0.841×φ+1.525×φ2=0.064×φ−0.841×φ+1.525×φ+1.46.
