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.
