    • An organic light-emitting display apparatus may include: a planarization layer disposed on a substrate and covering a plurality of thin film transistors; pixel electrodes, each comprising a light emission portion and anon-light emission portion, the light emission portion being arranged on the planarization layer in a first grid pattern; via-holes, each connecting one thin film transistor and one pixel electrode through the planarization layer, and arranged in a second grid pattern offset from the first grid pattern; dummy via-holes spaced apart from the via-holes; a pixel-defining layer (PDL) disposed on the planarization layer and covering 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 comprising an emissive layer; and an opposite electrode disposed on the organic layer.
    • 有机发光显示装置可以包括:设置在基板上并覆盖多个薄膜晶体管的平坦化层; 每个像素电极包括发光部分和阴极发射部分,所述发光部分以第一格子图案布置在所述平坦化层上; 通孔,每个通过所述平坦化层连接一个薄膜晶体管和一个像素电极,并且以与所述第一格栅图案偏移的第二格栅图案布置; 与通孔间隔开的虚拟通孔; 设置在平坦化层上并覆盖像素电极的通孔,虚拟通孔和非发光部分的像素限定层(PDL); 设置在所述发光部分上并包括发光层的有机层; 以及设置在有机层上的相对电极。
