Abstract: A display device in one example includes a substrate including an active area and a non-active area adjacent to the active area, a plurality of sub pixels disposed in the active area and each including a plurality of transistors, a first passivation layer covering the plurality of transistors, a planarization layer covering the first passivation layer, a second passivation layer covering the planarization layer, an adhesive layer disposed on the second passivation layer, and a plurality of light emitting diodes disposed on the adhesive layer. The first passivation layer and the second passivation contact with each other in the non-active area, so as to seal an end portion of the planarization layer.
