Abstract

A transverse electric field type liquid crystal display panel includes a pair of substrates opposed with a liquid crystal layer interposed therebetween. A plurality of sub-pixels having at least one curved portion in a display area are provided in a matrix on one side of the pair of substrates, and a pair of electrodes having at least one curved portion are formed in the plurality of sub-pixels. A light shield layer shielding a non-display area positioned on an outer peripheral side of the display area and between the plurality of sub-pixels is formed on the other side of the pair of substrates. The light shield layer of the non-display area is formed in a shape in which the outermost peripheral side of the display area is rectangular.

a light shield layer provided outside the display area,

wherein the light shield layer is formed to shield at least an innermost portion of the first side of a sub-pixel, among the plurality of sub-pixels, arranged at an end portion of the display area in the first direction and an innermost portion of the second side of a sub-pixel, among the plurality of sub-pixels, arranged at the other end portion of the display area, and

wherein the sub-pixels of an outermost peripheral side of the display area have an area wider than that of the other sub-pixels.
