Abstract: A micro LED display panel according to the present disclosure includes a substrate including a light emitting region and a driving region; a micro LED arranged in the light emitting region on the substrate, a transistor element arranged in the driving region on the substrate and driving the micro LED, a first connection wiring electrically connecting the micro LED and the transistor, and a color adjustment layer arranged in the light emitting region under the substrate. The micro LED display panel according to the present invention can form the micro LED and the transistor element for driving the micro LED on a growth substrate such as a sapphire substrate together on the same plane so that the micro LED does not require a transfer process, and it is possible to manufacture polysilicon when manufacturing the micro LED, and can simplify the process.
