Abstract: A display apparatus includes a substrate including a first area, and a second area adjacent to the first area; first to third light-emitting diodes that are arranged in the first area and include a color emission layer; an encapsulation layer overlapping the first to third light-emitting diodes, and including an inorganic layer and an organic layer; a first light shielding wall portion disposed on the encapsulation layer, the first light shielding wall portion including a 1-1-th opening portion, a 1-2-th opening portion, and a 1-3-th opening portion corresponding to the first to third light-emitting diodes, respectively; and a second light shielding wall portion disposed on the encapsulation layer and overlapping the second area. The first light shielding wall portion and the second light shielding wall portion are spaced apart from each other in a plan view.

Abstract: A display apparatus includes: a first pixel electrode in a display area; a pixel defining layer with a first pixel opening defined in the pixel defining layer exposing a center of the first pixel electrode; an emission layer over the first pixel electrode and configured to emit light in a first wavelength band; an opposite electrode over the emission layer; a second substrate over the first substrate such that the opposite electrode is between the first substrate and the second substrate; a bank over a bottom surface of the second substrate in a direction to the first substrate, a first opening defined in the bank overlapping with the first pixel opening and a first additional opening defined in the bank overlapping with the peripheral area, a first quantum dot layer in the first opening; and a bonding member bonding the first substrate and the second substrate to each other.
