Abstract: A display apparatus includes a light-emitting element, an encapsulation layer covering the light-emitting element, a bank on the encapsulation layer and including an opening corresponding to the light-emitting element, and a quantum-dot layer in the opening of the bank. Roughness of a lower surface of the quantum-dot layer which is closest to the encapsulation layer is different from roughness of an upper surface of the quantum-dot layer which is furthest from the encapsulation layer.
