Abstract
A micro light emitting diode (LED) display device includes a substrate, micro LED dies, a protection layer, and a funnel-tube structure array. The micro LED dies are located on the substrate. The protection layer covers the micro LED dies and the substrate. The funnel-tube structure array is located on the protection layer and includes funnel-tube structures. Each of the funnel-tube structures has a top surface facing away from the protection layer. The funnel-tube structures respectively overlap the micro LED dies in a vertical direction, and widths of the funnel-tube structures are gradually increased from the protection layer to the top surfaces of the funnel-tube structures.
