Disclosed is a driver for a display device, which is improved to stably sense pixels. The driver includes a multiplexer configured to output the sensing signal of a first input stage or second input stage, a first switch configured to switch a connection between an odd channel and the first input stage, a second switch configured to switch a connection between an even channel and the second input stage, and a switching circuit configured to switch a connection between a common power line and the first input stage or the second input stage.
