Abstract: A display panel includes a plurality of scan lines that receive scan signals, a plurality of data lines that receive data signals, lines that receive masking signals according to the scan signals, and a plurality of pixels respectively connected to the plurality of scan lines and the plurality of data lines. The error detection circuit receives the scan signals that are transmitted through the plurality of scan lines, and outputs an error detection signal based on the scan signals. Power is not supplied to the plurality of pixels when the error detection signal is at an activated level.
