Abstract: An electronic device includes a base layer, a plurality of first electrodes on the base layer, a pixel definition layer on the first electrodes and including a plurality of openings that expose a portion of the first electrodes,, a plurality of light emitting layers on the first electrodes, a plurality of patterns on the pixel definition layer, a second electrode on the light emitting layers, and an encapsulation layer on the patterns and the second electrode. The patterns are disposed between the light emitting layers when viewed in a plane, and each of the patterns has a width from about 3 micrometers to about 4 micrometers.
