Liquid crystal display panel
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.
