Abstract
A micro-LED display panel including a substrate, a plurality of micro-LEDs, and a plurality of reinforced structures is provided. The micro-LEDs are disposed at a side of the substrate, wherein each of the micro-LEDs comprises an epitaxial layer and an electrode layer electrically connected to the epitaxial layer, and the electrode layer are located between the epitaxial layers and the substrate. Each of the micro-LEDs is electrically connected to the substrate through the corresponding electrode layer. Each of electrode layers includes a first electrode and a second electrode. The reinforced structures are disposed between the micro-LEDs and the substrate respectively, and each of the reinforced structures is located between the corresponding the first electrode and the second electrode. A Young's modulus of each of reinforced structures is smaller than a Young's modulus of the corresponding electrode layer.
