Abstract

A method of manufacturing a display apparatus includes: forming a display element layer above a lower substrate, where the display element layer includes first to third display elements; forming an encapsulation layer on the display element layer; forming first partition walls on the encapsulation layer to define first to third color regions, where the first to third color regions overlap the first to third display elements, respectively, in a view in a direction perpendicular to the lower substrate; forming second partition walls on the first partition walls; forming a quantum dot layer, which includes forming a second color quantum dot layer in the second color region and forming a third color quantum dot layer in the third color region; and removing the second partition walls.
