发明名称 ワイヤグリッド偏光板及び投影型映像表示機器
摘要 A wire grid polarizing plate (10) has a substrate (11) having a concavo-convex structure extending in a particular direction on its surface, and a conductive material (12) provided to be distributed on one side surface (11b) of a convex portion (11a) of the concavo-convex structure. Further, in the wire grid polarizing plate (10), in a cross-sectional view in the perpendicular direction to the extension direction of the concavo-convex structure, a pitch P1 that is a distance between two adjacent convex portions (11a) is set at 120 nm or less, and a convex-portion height (H) that is a difference in height between a highest portion (11c) of the convex portion (11a) and a lowest portion (11e) of a concave portion (11d) is set at 0.8 time to 1.3 time the pitch P1. With the wire grid polarizing plate (10) in a liquid crystal display device, high image quality can be achieved.
