Abstract
A light emitting device includes a substrate and a light emitting layer over the substrate, the light emitting layer. The light emitting layer has a light emitting pixel array including a plurality of light emitting pixels and a spacer. The spacer is configured to separating the plurality of light emitting pixels. Each light emitting pixel has a light emitting material and an electrode between the light emitting material and the substrate. The spacer has a bump having a curved surface extruding away from the substrate, and the bump covers a peripheral region of the electrode.
