Abstract
An active matrix type liquid-crystal display device of IPS mode has its aperture ratio enhanced, thereby to realize an image display which has a wide angle of vision and which is clear and bright. A pixel portion (in FIG. 2) in the liquid-crystal display device comprises a TFT (115) which includes a semiconductor film formed over a substrate, and gate electrodes formed on a first insulating layer, a gate wiring line (104) which is formed on the first insulating layer, a common wiring line (113) which crosses the gate wiring line (104) through a second insulating layer, a pixel electrode (112) which is formed on the second insulating layer and which is connected with the TFT (115) of the pixel portion, a signal wiring line (106) which is formed so as to underlie the common wiring line (113) through the second insulating layer, and a connecting electrode (111) which is formed on the second insulating layer. The pixel electrode (112) and the common wiring line (113) are arranged so as to generate an electric field parallel to the plane of the substrate, and the signal wiring line (106) and the semiconductor film are connected through the connecting electrode (111).
