Abstract: Provided is a method of detaching a display module. The method of detaching the display module includes providing a carrier substrate, forming a display module, which is divided into a first area and a second area, on the carrier substrate, disposing a protective film covering the first area and exposing the second area on the display module, performing a first detaching process of detaching the second area from the carrier substrate by using a first detaching unit, and performing a second detaching process of detaching the protective film and the display module from the carrier substrate by using a second detaching unit.
