Abstract: An organic light emitting diode (OLED) display includes: a first electrode around a center point of a virtual tetragon, e.g., a virtual square; second electrodes around a first vertex and a second vertex diagonal to the first vertex of the virtual square, the second electrodes being separated from each other and with the center point of the virtual square interposed therebetween; third electrodes around a third vertex and a fourth vertex of the virtual square, the third electrodes being separated from each other and with the center point of the virtual square interposed therebetween; a pixel defining layer partially on the first electrode, the second electrodes, and the third electrodes, and partially exposing the first electrode, the second electrodes, and the third electrodes; and four spacers disposed as islands on the pixel defining layer and corresponding to four sides of the virtual square.

Abstract: A manufacturing method of a wire including: forming a lower layer on a substrate; forming a middle layer on the lower layer; forming an upper layer on the middle layer; forming, exposing, and developing a photoresist layer on the upper layer to form a photoresist pattern; and etching the upper layer, the middle layer, and the lower layer by using the photoresist pattern as a mask to form a wire such that the upper layer covers an end of the middle layer.
