The invention discloses a circuit for eliminating a shutdown afterimage, a control method of the circuit and a liquid crystal display device. Voltage of a direct current power supply end is divided through a voltage division module, and then a switch control signal is generated. The control module outputs a conduction control signal to the charging and discharging module and outputs a pull-up control signal to the level conversion module only when the voltage of the switch control signal is smaller than the reference voltage. The charging and discharging module discharges when receiving the conduction control signal and provides a high-level voltage signal for the level conversion module. The level conversion module works when receiving the pull-up control signal, and provides a high-levelvoltage signal output by the charging and discharging module to a TFT in the liquid crystal display device to control the TFT to be turned on. Thus, through discharging of the charging and discharging module, it is guaranteed that the voltage provided for the level conversion module cannot rapidly decrease along with power failure of an external direct-current power source, a TFT is fully opened,charges are fully released, the phenomenon that the charges remain is avoided, and the shutdown afterimage eliminating effect is improved.
