The invention provides a micro LED display panel, with sub-pixel area (2) disposed with a micro LED (3) of a size smaller than the size of the sub-pixel area (2), and using a reflective lens layer (5) disposed below the micro LED (3) to reflect the light emitted by micro LED (3) to the area surrounding the micro LED (3) inside the sub-pixel area (2), and thereby expanding the illuminating area inside the sub-pixel area (2) to enhance the display quality and reduce cost.
