Abstract
The present invention provides a liquid crystal display device with a high aperture ratio in a pixel region while securing a required storage capacitance. A liquid crystal display device comprises in this order: a thin film transistor array substrate; a liquid crystal layer; and a counter substrate, the thin film transistor array substrate comprising: source lines and gate lines that are disposed in a lattice form; a storage capacitor wiring; a transparent pixel electrode disposed in a pixel region; a thin film transistor comprising a gate electrode, a source electrode, and a drain electrode; a gate insulating film between the gate electrode and the source and drain electrodes in layer sequence; and an interlayer insulating film between the source and drain electrodes and the transparent pixel electrode in layer sequence, wherein a first transparent electrode in a lower layer of the drain electrode and a second transparent electrode connected to the storage capacitor wiring are disposed on the gate insulating film, and the second transparent electrode faces the transparent pixel electrode with the interlayer insulating film therebetween.
