Abstract: A driver includes a dummy stage and one or more additional stages coupled to the dummy stage. The dummy stage includes a first transistor coupled between an input terminal and an output terminal. The first transistor includes two electrodes forming at least a first capacitor to store at least a portion of static electricity received through the input terminal. The one or more additional stages output gate signals, which may be received, for example, by a display device.

Abstract: A gate driving circuit includes a plurality of stages. Adjacent two stages from among the plurality of stages constitute a stage pair. The adjacent two stages in the stage pair include switching elements connected with each other. When a carry signal of an N-th stage in the stage pair has a defect, the N-th stage is configured to output a carry signal of an (N+1)-th stage in the stage pair. N is a positive integer. When a defect has occurred at a carry signal of a stage in a stage pair, the carry signal of the stage having the defect may be repaired by a carry signal of another stage in the stage pair.
