The present disclosure provides an overcurrent protection circuit, an overcurrent protection method, a clock signal generation circuit and a display device. The overcurrent protection circuit includes N first overcurrent detection circuits, N second overcurrent detection circuits, a first signal generation circuit, a second signal generation circuit, a first level switching circuit, a second level switching circuit and a control circuit. The first signal generation circuit is configured to output a first control signal to the first level switching circuit upon the receipt of a first overcurrent indication signal. The second signal generation circuit is configured to output a second control signal to the second level switching circuit upon the receipt of a second overcurrent indication signal. The control circuit is configured to provide an OFF control signal to an nth output control module after a predetermined time period upon the receipt of a third control signal and/or a fourth control signal, where N is a positive integer, and n is a positive integer smaller than or equal to N.
