Abstract
A manufacturing method of a flexible display apparatus includes forming a sacrificial layer on a carrier, forming a flexible substrate on the sacrificial layer, forming a display element on the flexible substrate, forming a first protection layer on the display element, forming, on the first protection layer, a second protection layer, which has an opposite sign of a thermal expansion coefficient to the first protection layer, separating the flexible substrate from the carrier by removing at least a portion of the sacrificial layer, and separating the first protection layer from the first protection layer.
