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.
