Abstract: An organic light-emitting display apparatus includes a pixel-defining layer configured to surround a plurality of pixels while exposing an emission area of the plurality of pixels on a substrate; and a spacer provided on the pixel-defining layer and configured to allow a mask to be placed on the spacer, the mask being arranged for deposition of an emission layer in the emission area, wherein a distance in a plane direction between the spacer and each of the plurality of pixels is within 1 μm. A color mixture between pixels may be prevented by suppressing the shadow phenomenon in deposition of an emission layer such that performance and reliability of the organic light-emitting display apparatus may be significantly improved.

Abstract: A display apparatus includes a substrate having a first transmissive area, a second transmissive area, a pixel area between the first transmissive area and the second transmissive area, a first pixel electrode in the pixel area, a first intermediate layer disposed on the first pixel electrode to emit light of a first color and an insulating layer covering edges of the first pixel electrode and defining a first emission area through a first opening exposing a portion of the first pixel electrode. A first partition wall is disposed on the insulating layer between the first emission area and the first transmissive area. A second partition wall is disposed on the insulating layer between the first emission area and the second transmissive area. An opposite electrode is disposed on the first intermediate layer in the pixel area and partially contacts the first partition wall and the second partition wall.
