Abstract: A display device includes an auxiliary electrode in order to prevent uneven brightness by the voltage drop. The display device further includes an under-cut region formed by stacked insulating layers. In the display device, the under-cut region is completely filled by filler due to changing a shape of the auxiliary electrode, so that the quality of the displaying image is improved. Also, in the display device, the contact area between an upper electrode of a light-emitting structure and the auxiliary electrode is increased, so that the reliability and the degree of integration are improved.

Abstract: A display device including color filters overlapping each other on a non-emitting area of an upper substrate which is opposite to a lower substrate is provided. In the display device, color filters disposed close to a white emitting area include a same material, and the color filters extend a greater distance onto a non-emitting area disposed near the white emitting area, relative to distances extended onto other non-emitting areas. Thus, the display device may prevent light-leakage from the white emitting area.

Abstract: A display device including emitting areas is provided. The emitting areas of the display device may realize a different color each other. The display device includes light-emitting structures on the emitting areas. The adjacent light-emitting structures have different heights with respect to the lower substrate, such that a size of a non-emitting area between the adjacent emitting areas is reduced.
