ORGANIC LIGHT EMITTING DISPLAY DEVICE

An organic light-emitting display comprises a substrate having a plurality of subpixels arranged in a row direction and a column direction crossing the row direction; a plurality of first electrodes respectively allocated to the plurality of subpixels and comprising a first sub-electrode arranged in a (3n-2) column, a second sub-electrode arranged in a (3n-1) column, and a third sub-electrode arranged in a 3n column (where n is a natural number of 1 or more); and a bank having an opening exposing the plurality of first electrodes, wherein the first sub-electrode has a convex part protruded toward the third sub-electrode that has a concave part corresponding to the convex part. 一种有机发光显示器包括：基板，具有在行方向和与行方向交叉的列方向上布置的多个子像素；多个第一电极，分别分配给多个子像素，并且包括布置在第(3n-2)列中的第一子电极、布置在第(3n-1)列中的第二子电极、以及布置在第3n列中的第三子电极(其中n是1或更大的自然数)；以及具有暴露多个第一电极的开口的堤部，其中，第一子电极具有朝向第三子电极突出的凸部，第三子电极具有与凸部对应的凹部。
