Patent ID: 7545449

Claim:
A liquid crystal display device comprising: a substrate; a plurality of scanning lines formed in parallel with each other on an upper side of said substrate in one direction; a plurality of data lines formed in parallel with each other and orthogonal to said scanning lines on said upper side of said substrate; a thin film transistor formed in a vicinity of each intersection of said scanning lines and said data lines and having a semiconductor thin film, a gate electrode connected to one of said scanning lines, a gate insulation film disposed between said semiconductor thin film and said gate electrode, a source electrode, and a drain electrode connected to one of said data lines; pixel electrodes each connected to the source electrode of said thin film transistor; auxiliary capacitive electrodes each having an overlap region that overlaps with said pixel electrodes and a non-overlap region that does not overlap with said pixel electrodes and forming an auxiliary capacitance with said pixel electrodes; a first insulating film arranged between said auxiliary capacitive electrodes and said data lines; and a second insulating film arranged between said pixel electrodes and said auxiliary capacitive electrodes, wherein said auxiliary capacitive electrodes include a light-shielding metal film and a transparent conductive film having a larger width than the width of said light-shielding metal film and overlapping said data line via said first insulating film.
