Abstract
An emissive display device according to an embodiment includes: a substrate; a transistor disposed on the substrate; an insulating layer disposed on the transistor; a pixel electrode disposed on the insulating layer and electrically connected to the transistor; and a partition disposed on the insulating layer and covering at least an edge of the pixel electrode to expose a center of the pixel electrode. The partition includes a first partition in contact with a side surface of the pixel electrode, and a second partition in contact with an upper surface of the pixel electrode.
