Abstract: A display apparatus including a light-emitting device and a method of forming the same are provided. The light-emitting device may be electrically connected to the driving circuit. A first planarization layer may be disposed on the driving circuit, a second planarization layer may be disposed on the first planarization layer, and the light-emitting device may be disposed on the second planarization layer. An upper surface of the second planarization layer toward the light-emitting device may be parallel with a surface of a device substrate supporting the light-emitting device and the driving circuit. Thus, in the display apparatus and the method of forming the same, decreasing the quality of an image due to differences in the generation position of the light emitted from the light-emitting device may be prevented.

Abstract: A display device having a reduced bezel area is discussed. The display device can include a base substrate having a first area and a second area disposed outside the first area and being bent, a first driving transistor part disposed on the first area of the base substrate, a first light emitting element connected to the first driving transistor part in the first area, at least one first trench part formed by being recessed in the second area of the base substrate, a second driving transistor part disposed in the at least one first trench part, and a second light emitting element connected to the second driving transistor part in the second area. As such, the display device is configured to emit light even in the second area which is bent at the edge of the display panel.
