Abstract
A wire grid polarizing plate () has a substrate () having a concavo-convex structure extending in a particular direction on its surface, and a conductive material () provided to be distributed on one side surface () of a convex portion () of the concavo-convex structure. Further, in the wire grid polarizing plate (), in a cross-sectional view in the perpendicular direction to the extension direction of the concavo-convex structure, a pitch Pthat is a distance between two adjacent convex portions () is set at 120 nm or less, and a convex-portion height (H) that is a difference in height between a highest portion () of the convex portion () and a lowest portion () of a concave portion () is set at 0.8 time to 1.3 time the pitch P. With the wire grid polarizing plate () in a liquid crystal display device, high image quality can be achieved.
