Patent ID: 7483009

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 provided between the signal line and the pixel electrode, the gap having a width not less than 1 μm and not more than a value at which display unevenness is not sufficiently improved relative to aperture ratio; a size of the gap between the signal line and the pixel electrode is set to provide a desired ΔΔβ value which is interrelated with display unevenness; the desired ΔΔβ value is not more than 0.08; the desired ΔΔβ value is related to a difference in parasitic capacitance between the pixel electrode and the signal line and affects a difference in an effective value (Vd) of pixel potential of the pixel electrode; and an upper limit of the gap is 15 μm.
