Abstract: A display device includes a display panel including a flat portion and a bending portion located at a side of the flat portion, an optical film attached on the flat portion of the display panel, and a bending protection layer covering at least a part of the bending portion and contacting one edge of the optical film. The edge of the optical film includes an upper surface, a lower surface and a side surface, the lower surface of the optical film faces an upper surface of the display panel, at least a part of the side surface of the optical film contacts the bending protection layer, and at least a part of the side surface of the optical film protrudes more, as closer to the upper side.

Abstract: A display device includes a display panel including a plurality of pixels which display an image, a panel driver which generates a driving voltage based on a plurality of feedback voltages sensed from the display panel to drive the display panel, and a plurality of sensing lines which are connected to the pixels to sense the feedback voltages, respectively, and apply the sensed feedback voltages to the panel driver. The panel driver generates an average feedback voltage corresponding to an average of the feedback voltages and generates the driving voltage based on the average feedback voltage.
