Patent ID: 7602358

Claim:
A display device substrate, comprising: one or more pixel electrodes each of which is provided on each intersection of a signal line and a scanning line that are provided on an insulating substrate; and an interlayer insulating film stacked between the signal line and the pixel electrode, wherein in view of a vertical direction with respect to a surface of the insulating substrate, the signal line is provided on an area on which the pixel electrode is not provided, and a gap is provided between the signal line and the pixel electrode; and wherein the signal line is covered by a light shielding film having an insulating property that contacts the signal line; wherein the interlayer insulating film is provided on the light shielding film; wherein the pixel electrode is provided on the interlayer insulating film; and wherein in view of a vertical direction with respect to the surface of the insulating substrate, a surface of the signal line and the gap provided between the signal line and the pixel electrode are covered by the light shielding film, wherein in view of a vertical direction with respect to a surface of the insulating substrate, the pixel electrode, the interlayer insulating film, the light-shielding film, and the signal line are provided in this order; wherein the gap includes an area in which no voltage is applied to a region between the pixel electrode and the signal line; and wherein the gap is set to be within a range of from not less than 2 μm to not more than 20 μm.
