Abstract
A display device includes a substrate, a plurality of first electrodes disposed on the substrate, a pixel defining layer disposed on the substrate, and defining a plurality of opening areas by exposing a portion of an upper surface of each of the plurality of first electrodes, a spacer disposed on the pixel defining layer and disposed between two adjacent opening areas among the plurality of opening areas, a groove extending into the spacer, a first common layer covering the plurality of first electrodes, the pixel defining layer, and the spacer, a plurality of light emitting layers disposed on the first common layer to overlap each of the plurality of opening areas, and a second electrode covering the plurality of light emitting layers and the first common layer. The groove at least partially overlaps with an imaginary straight line connecting two points located at the shortest distance between adjacent opening areas.
