Abstract: A TFT substrate includes a first active pattern, a first gate insulation, and a first gate. A second gate is on a second gate insulation covering the first gate. A source connection electrode contacts a source region of the first active pattern. A drain connection electrode contacts its drain region. A second active pattern is on a first insulation covering the second gate. A third gate insulation covers the second active pattern. A third gate is disposed on the third gate insulation. A second insulation interlayer covers the third gate. A first source, a first drain, a second source, and a second drain are disposed on the second insulation interlayer. The first source and the first drain contact the source connection electrode and the drain connection electrode. The second source and the second drain contact a source region and a drain region of the second active pattern.

Abstract: A light-emitting diode includes a first electrode part, a second electrode part disposed on the first electrode part, and a semiconductor junction structure disposed between the first electrode part and the second electrode part. The semiconductor junction structure may include a first semiconductor layer, a second semiconductor layer, a third semiconductor layer, an optical layer, and an active layer. Any one of the optical layer and the active layer may be disposed between the first semiconductor layer and the second semiconductor layer, and another one of the optical layer and the active layer may be disposed between the second semiconductor layer and the third semiconductor layer. The optical layer may include a porous layer and a non-porous layer disposed on the porous layer, and in a direction perpendicular to the thickness direction, a first width of the porous layer may be greater than a second width of the non-porous layer.
