Abstract:
1. An organic light-emitting display apparatus comprising: 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 equidistant from all of the light-emitting portions diagonally adjacent and around 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 comprising 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 wherein the plurality of pixel electrodes are patterned in a first direction and a second direction perpendicular to the first direction, and each of the plurality of via-holes is formed at a position farthest from outer limits of the light-emitting portions of the plurality of pixel electrodes that are adjacent in the first direction and the second direction and disposed around the via-hole; wherein each of the plurality of via-holes is formed at an intersection of first and second straight lines, the first straight line connecting central points between adjacent pairs of the light-emitting portions that are adjacent in the first direction and disposed around the via-hole and the second straight line connecting central points between adjacent pairs of the light-emitting portions that are adjacent in the second direction and disposed around the via-hole.
