Abstract:
1. A display device comprising: a first substrate having an insulating surface; a switching element over the first substrate; an insulator layer over the switching element; a pixel electrode electrically connected to the switching element, over the insulator layer; a dummy layer overlapping with the switching element, over the insulator layer; and a columnar spacer between the first substrate and a second substrate, wherein the pixel electrode and the dummy layer are formed of the same material, wherein the switching element comprises a semiconductor layer with at least one channel formation region therein, wherein the dummy layer overlaps the at least one channel formation region in the semiconductor layer, wherein the dummy layer overlaps the columnar spacer, wherein the pixel electrode is formed on and in contact with the insulator layer, wherein the columnar spacer is formed on the second substrate, wherein the dummy layer is in an electrically floating state, and wherein the dummy layer has a pattern shape which is a cross-shape.
