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.

Abstract: In a liquid crystal display device, an upper electrode and a drain electrode are reliably connected to each other electrically, with preventing or suppressing an occurrence of an aperture ratio loss, or sufficiently reducing a parasitic capacitance between the scanning line and the lower electrode. An interlayer resin film is formed on a drain electrode, with a hole being formed on the interlayer resin film, and on the drain electrode exposed to a bottom portion of the hole, an island-shaped electrode is formed separately from a lower electrode. Moreover, on the island-shaped electrode, an inter-electrode insulating film is formed, a contact hole is formed in the inter-electrode insulating film, and an upper electrode is formed on the island-shaped electrode exposed to a bottom portion of the contact hole.
