Abstract: A panel substrate includes a base substrate including a plurality of sub-pixel areas; a thin-film transistor disposed over each of the plurality of sub-pixel areas; an interlayer insulating film disposed over the thin-film transistor; a first optical functional layer disposed on the interlayer insulating film so as to prevent transmission and reflection of light; a second optical functional layer disposed on the first optical functional layer, wherein the second optical functional layer has first patterns and second patterns, wherein the first pattern has adhesiveness while the second pattern has less adhesiveness than the first pattern; and a plurality of micro-LEDs respectively disposed on the first patterns of the second optical functional layer.
