Abstract
An array substrate of a display device, the array substrate: a substrate having a first region and a second region spaced apart from the first region; a blocking layer located on the substrate; a first electrode located on the blocking layer in the second region; an insulating film located on the blocking layer to cover the first electrode; a second electrode located on the insulating film to overlap the first electrode; and a third electrode overlapping the first electrode between the substrate and the blocking layer. Accordingly, it is possible to reduce an area that is occupied by a storage capacitor in a pixel region and to achieve high luminance by increasing the aperture ratio, by providing a structure and method of increasing a storage capacitance of the same area.
