| 1. 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.
