Abstract
A three-in-one RGB mini-LED device includes a substrate, a second electrical semiconductor layer, a plurality of multiple-quantum well layers, a plurality of first electrical semiconductor layers, and a plurality of mirrors. The second electrical semiconductor layer is disposed on the substrate. The plurality of multiple-quantum well layers are disposed on the second electrical semiconductor layer. An area of each of the plurality of multiple-quantum well layers is smaller than an area of the second electrical semiconductor layer, and a region on the second semiconductor layer is not covered by the plurality of multiple-quantum well layers.
