Abstract:
Provided is a substrate for liquid crystal display to execute effective viewing angle control while preventing a liquid crystal display device from becoming heavy and thick and preventing an aperture ratio from decreasing, by realizing effective vision control without using a vision control element or a vision control pixel. The substrate for liquid crystal display includes a polygonal pixel or a polygonal sub-pixel and linear patterns. The polygonal pixel or the polygonal sub-pixel has parallel sides opposite to each other in a plane shape. The linear patterns are included on parallel sides opposite to each other of the polygonal pixel or the polygonal sub-pixel and allows skew light to pass therethrough.
