Abstract
A display module is provided. The display module includes: a substrate; a thin film transistor (TFT) layer formed on one surface of the substrate; and a plurality of micro LEDs disposed on the TFT layer. The plurality of micro LEDs are transferred from a transfer substrate to the TFT layer by a laser beam radiated to the transfer substrate through openings of a mask. The openings correspond to regions in which the respective micro LEDs of the transfer substrate are arranged and the openings correspond to a width, a length, or a unit area of each of the micro LEDs.
