Abstract
A micro LED display device includes a circuit substrate, an epitaxial structure layer and a metal reflective layer. The circuit substrate includes a display area and a non-display area adjacent to the display area. The epitaxial structure layer includes a first surface facing the circuit substrate, a second surface away from the circuit substrate, and a plurality of ion implantation regions facing the circuit substrate. The ion implantation regions define a plurality of micro LED units spaced apart from each other. The first surface is a planar surface within the display area, and each groove in the second surface corresponds to one of the ion implantation regions. The metal reflective layer includes a plurality of reflective portions corresponding to the grooves. The reflective portions define a plurality of light transmission regions, and each light transmission region corresponds to one of the micro LED units.
