Abstract
In a pixel array substrate, scan lines intersect data lines to define first to third sub-pixel regions. First to third conductive parts are respectively disposed in the first to third sub-pixel regions. First to third capacitor electrodes are respectively disposed over the first to third conductive parts to form pixel storage capacitors. A spacer is disposed over the third capacitor electrode. At least one of a shape or a size of the third capacitor electrode is different from that of the first or second capacitor electrode.
