Abstract:
1. A liquid crystal display panel comprising: first substrate and second substrate configured to sandwich a liquid crystal layer and be disposed opposed to each other, a display sub-pixel and a viewing angle control sub-pixel being formed in the first substrate and the second substrate; a first polarizer configured to be provided on an outer surface side of the first substrate; and a second polarizer configured to be provided on an outer surface side of the second substrate and have an optical axis perpendicular to an optical axis of the first polarizer, wherein in the first substrate, for both the display sub-pixel and the viewing angle control sub-pixel, a lower electrode, an upper electrode that is formed with intermediary of an insulating layer between the upper electrode and the lower electrode and has a plurality of slit apertures, and a first alignment film that is formed on a surface of the upper electrode and in the slit apertures and is subjected to rubbing treatment parallel or perpendicular to the optical axis of the first polarizer are formed, in the second substrate, a second alignment film subjected to rubbing treatment parallel or perpendicular to the optical axis of the first polarizer is formed, and direction of the rubbing treatment for the first alignment film is inclined to at least one of a perpendicular line to extending direction of the slit aperture of the viewing angle control sub-pixel and an edge line of a slit end part of the slit aperture of the viewing angle control sub-pixel.
