The gate driver includes a plurality of gate lines connected to gates of the switch transistors, a plurality of reset lines connected to gates of the light sensor transistors, and a plurality of phase inverters each connected between a corresponding reset line and a gate line. Thus, when a gate voltage is applied to one of the plurality of gate lines, a reset signal with an inversed phase to the gate voltage may be applied to a corresponding reset line.
