Abstract: Provided is a gate driving unit including: a plurality of stages configured to be activated sequentially so as to generate gate signals; and a plurality of repair blocks having sizes smaller than the corresponding stages and configured to repair defects of the stages. Each of the repair blocks is disposed proximate to two or more stages so as to be configured to repair defects in the two or more stages.

Abstract: A flexible display is disclosed. In one aspect, the display includes at least one first pattern including a plurality of display elements configured to display an image and extending in a first direction. The display device also includes at least one second pattern extending in a second direction and overlapping at least a portion of the first pattern. The second pattern has a curved shape in the first direction and the second direction crosses the first direction. The first and second patterns form at least one cavity region defining a space therebetween and the first and second patterns form a mesh structure.

Abstract: A gate driving circuit includes: a plurality of stages to provide gate signals to gate lines of a display panel, a k-th stage, where k is a natural number greater than or equal to 2, from among the plurality of stages being configured: to receive a clock signal, a (k−1)th carry signal from a (k−1)th stage, a (k+1)th carry signal from a (k+1)th stage, a (k+2)th carry signal from a (k+2)th stage, a first voltage, and a second voltage, the clock signal being a pulse signal in which a high voltage and a third voltage appear periodically, and the third voltage having a lower voltage level than those of the first voltage and the second voltage; and to output a k-th gate signal and a k-th carry signal.
