Abstract
An organic light emitting diode display is provided that may include a first substrate, a plurality of electrodes on the first substrate and spaced apart from each other, a pixel defining layer on the plurality of electrodes, spacers on the pixel defining layer, and a second substrate on the spacers. The pixel defining layer includes a plurality of openings spaced apart from each other and respectively open to the plurality of electrodes. The spacers on the pixel defining layer are at crossing points of a plurality of virtual lines, the spacers crossing spaces between adjacent openings of the plurality of openings.
