Abstract: A display device and a method of driving the same. Characteristics of driving transistors disposed in subpixels of a display panel are sensed and compensated for, thereby improving the image quality of the organic light-emitting display device. Changes in a data voltage between a point in time at which a blank period starts and a period in which the sensing of the driving transistors starts are reduced or minimized, thereby reducing deviations in the sensing of the characteristics of the driving transistors.

Abstract: In a display device, an edge portion of a pixel electrode is modified. A valley is provided in an overcoat layer located below the pixel electrode. The edge portion of the pixel electrode is configured to be curved or bent onto the overcoat layer. As a result, the aperture ratio of the display device can be increased, and an image abnormality in the edge portion of the pixel electrode can be prevented.
