Abstract
A fabrication method of a display device includes the following steps: providing a light-emitting diode (LED) display device including an circuit substrate, first LEDs, and a second LED; detecting the LED display device, wherein the second LED cannot emit light normally; removing the second LED from the circuit substrate; providing a LED substrate; transferring a third LED of the LED substrate to a first transferring substrate; transferring the third LED on the first transferring substrate to a second transferring substrate; and electrically connecting the third LED on the second transposed substrate to the circuit substrate.
