An organic light emitting diode (OLED) display includes: a first electrode around a center point of 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.
