Abstract:
1. A display device comprising an active matrix substrate having a plurality of switching elements arranged in a matrix and an opposite substrate located opposite to said active matrix substrate through a display medium layer, wherein said active matrix substrate comprises: a plurality of connection terminals for sending drive signals to the switching elements, wherein the connection terminals are respectively electronically connected to, and led out from, the switching elements and are arranged in parallel with each other in a plan view; an interlayer insulating film disposed over the plurality of switching elements and over the plurality of connection terminals, wherein tips of the plurality of connection terminals are exposed along a horizontal end portion of the interlayer insulating film in the plan view; and a layer made of a pixel electrode material disposed on said interlayer insulating film and on the exposed tips of the plurality of connection terminals, the layer made of the pixel electrode material including a plurality of pixel electrodes, each of which is electrically connected to a corresponding switching element through a contact hole formed in said interlayer insulating film, wherein an opening is formed in said interlayer insulating film in a region between adjacent connection terminals at the horizontal end portion of said interlayer insulating film in the plan view, and a height of the interlayer insulating film between a horizontal end edge of the interlayer insulating film and a front edge of the opening that is adjacent to said horizontal end edge of the interlayer insulating film is lower than a height of the interlayer insulating film formed on an opposite side of the opening.
