    Abstract: A method of manufacturing a display device includes forming a buffer layer on a top surface of a substrate, forming an amorphous silicon layer on a top surface of the buffer layer, and forming a polysilicon layer by irradiating the amorphous silicon layer with a laser beam. A plurality of first protrusions are formed on the top surface of the polysilicon layer, and a plurality of second protrusions are formed on a surface of the buffer layer by transferring the shape of the polysilicon layer to the buffer layer. A gate insulator on the buffer layer is then formed in the shape of bumps of the second protrusions.

    Abstract: An organic light-emitting display having an improved aperture ratio, the organic light-emitting display including a rear electrode, an opposite electrode, and a pixel electrode between the rear electrode and the opposite electrode. Here, an insulating layer is interposed between the pixel electrode and the rear electrode, wherein the pixel electrode, the insulating layer, and the rear electrode are configured as a capacitor of the organic light-emitting display. In such a structure, as the capacitor is disposed in a light-emitting area where the pixel electrode exists, it is not necessary to provide an additional space for a capacitor, thus improving an aperture ratio of the display.
