A display panel includes a displaying area including pixels, a non-displaying area including a dummy pixel, and a switching circuit to transfer a data signal to the dummy pixel in response to a control signal. The display panel may compensate for defective pixels located in different data lines using only one dummy pixel column and may minimize an area (e.g., a dead space) including the dummy pixel column by including a distributor buffering a signal of an output line and a switching circuit selecting/providing a portion of a signal of the output line to a dummy data line.
