Abstract
A micro-LED display panel including a substrate, an anisotropic conductive film, and a plurality of micro-LEDs is provided. The anisotropic conductive film is disposed on the substrate. The micro-LEDs and the anisotropic conductive film are disposed at the same side of the substrate, and the micro-LEDs are electrically connected to the substrate through the anisotropic conductive film. Each of the micro-LEDs includes an epitaxial layer and an electrode layer electrically connected to the epitaxial layer, and the electrode layers comprises a first electrode and a second electrode which are located between the substrate and the corresponding epitaxial layer. A ratio of a thickness of each of the electrode layers to a thickness of the corresponding epitaxial layer ranges from 0.1 to 0.5, and a gap between the first electrode and the second electrode of each of the micro-LEDs is in a range of 1 μm to 30 μm.
