Abstract:
1. A liquid crystal display device, comprising: gate wiring and source wiring disposed in a lattice state; a switching element provided on each lattice point; a pixel electrode to be connected to a drain electrode of the switching element; an auxiliary capacitance electrode which is formed in the same manufacturing process as the gate wiring and disposed in parallel with the gate wiring so as to form a storage capacitance which is serially connected to the pixel electrode; and electrodes which are disposed in parallel at two different portions on an extension portion of the drain electrode of the switching element in an extending direction and connected to each other via a coupling portion to connect with the drain electrode, and a branch coupling portion which branches off from the coupling portion in-between, wherein: said electrodes disposed in parallel are connected to the pixel electrodes via through holes which are respectively formed in a layer insulating film, which is on said electrodes, and stacked via the auxiliary capacitance electrode and insulating film so as to respectively form the storage capacitances, and said pixel electrode is connected to said switching element through said electrodes disposed at two different portions on said extension portion of the drain electrode.
