Abstract
A micro LED display device includes a substrate, micro LED units and a transparent insulation layer. The substrate includes conductive pads and conductive connecting portions. The conductive pads are disposed on the substrate. Each of the micro LED units includes a semiconductor epitaxial structure and electrodes. The electrodes are disposed on the semiconductor epitaxial structure, and each of the electrodes is connected to one of the conductive connecting portions adjacent to each other. The transparent insulation layer is disposed on the substrate and covers the conductive pads, the conductive connecting portions and the micro LED units, and the transparent insulation layer is filled between the electrodes of each of the micro LED units. The transparent insulation layer relative to a surface on each of the semiconductor epitaxial structures is of a first thickness and a second thickness, and the first thickness is different from the second thickness.
