Abstract:
A display device comprising:a substrate; a gate line formed over the substrate; a first insulating film formed over the substrate and the gate line; a semiconductor film formed over the first insulating film; a drain electrode formed over the semiconductor film; a source electrode formed over the semiconductor film; a data line connected to the drain electrode and formed over the first insulating film; a second insulating film formed over the source electrode and the data line; a pixel electrode electrically connected to the source electrode and formed over the second insulating film; and a transparent conductive film connected to the data line through a contact hole formed in the second insulating film, the transparent conductive film being adapted to be electrically connected to an external drive circuit, wherein the transparent conductive film has a portion, which has a lower surface nearer to a surface of the substrate than a lower surface of the transparent conductive film in the contact hole.
