Patent ID: 8785940

Claim:
An organic light-emitting display apparatus, comprising: a planarization layer covering a plurality of thin film transistors formed on a substrate; a plurality of pixel electrodes, each comprising a light emission portion and a non-light emission portion, wherein the light emission portions ref the pixel electrodes are arranged on the planarization layer in a first grid pattern; a plurality of via-holes arranged in a second grid pattern which is offset from the first grid pattern, each via-hole connecting a respective one of the plurality of thin film transistors and a respective one of the plurality of pixel electrodes through the planarization layer; a plurality of dummy via-holes respectively spaced apart from the plurality of via-holes; a pixel-defining layer (PDL) formed on the planarization layer so as to cover the via-holes, the dummy via-holes, and the non-light emission portion of the pixel electrodes; an organic layer disposed on the light emission portion and including an emissive layer; and an opposite electrode disposed on the organic layer.
