A dual-output flyback voltage conversion circuit and a display device are provided. The dual-output flyback voltage conversion circuit includes an input module, a voltage transformation module, an output module, and a feedback module. The input module is used for rectifying and filtering an input voltage. The voltage transformation module is used for performing a voltage conversion process on the input voltage which is obtained after rectifying and filtering. The output module is used for outputting a first output voltage and a second output voltage according to conversion voltages. The feedback module is used for controlling the voltage transformation module to output the input voltage which is obtained after rectifying and filtering according to the first output voltage and the second output voltage.
