Abstract
A liquid crystal display device includes a counter substrate and an active matrix substrate, and a liquid crystal layer that is provided between the counter substrate and the active matrix substrate. The active matrix substrate includes gate interconnect lines, data interconnect lines, a thin film transistor, a pixel electrode that is connected to the thin film transistor via a through hole, a common electrode, and an interlayer insulating layer that is disposed between the pixel electrode and the common electrode. Also, a photo spacer for providing a constant spacing between the counter substrate and the active matrix substrate is provided inside the liquid crystal layer, and equipotential lines having a voltage less than a threshold value are formed inside the photo spacer.
