Abstract
An organic light-emitting display apparatus includes: a plurality of thin film transistors (TFTs); a planarization layer covering the plurality of TFTs; a plurality of pixel electrodes formed on the planarization layer, each of the pixel electrodes being connected to a corresponding one of the plurality of TFTs using a via-hole passing through the planarization layer and having a light-emitting portion and a non-emitting portion, and each of the via-holes being located at a point farthest from each of the light-emitting portions surrounding the via-hole; a pixel defining layer formed on the planarization layer to respectively cover each of the via-holes and the non-emitting portions; organic layers, each organic layer including an emission layer and being disposed in a corresponding one of the light-emitting portions; and a counter electrode disposed on each of the organic layers.
