PROBLEM TO BE SOLVED: To provide a discharge circuit which intercepts occurrence of after-image by discharging a gate off voltage being a negative voltage to a ground voltage level at high speed when an external voltage is shut off and is not applied to a display panel due to a standby mode of a display device, impulses, or power failure, and a display device including the discharge circuit. SOLUTION: The discharge circuit for a device including a drive circuit operating by an input negative voltage includes: a discharge unit connected between a first input terminal receiving the negative voltage and a second input terminal receiving a ground voltage, and configured to discharge the negative voltage to the ground voltage of the second input terminal in response to a control signal; and a control unit connected between the first input terminal and a third input terminal receiving an operation voltage corresponding to a normal operation mode and an abnormal operation mode of the drive circuit, and configured to generate the control signal in response to an operation signal for determining an operation state and a non-operation state in the normal operation mode of the drive circuit.
