Provided a pixel circuit, a method for driving a pixel circuit, a display panel, and a display apparatus. The pixel circuit applied in a display panel includes a data writing module, a drive transistor, a leakage current alleviation module, a first power supply terminal, and a data signal terminal. The data writing module configured to write data signal of the data signal terminal to gate of the drive transistor in data writing stage; the leakage current alleviation module configured to transmit leakage current generated by the data writing module to first power supply terminal in leakage current alleviation stage; and the drive transistor configured to drive a light-emitting element to emit light in light emission stage. The leakage current alleviation stage located at least between the data writing stage and the light emission stage, enhancing the luminance accuracy of the light-emitting element and the display uniformity of the display panel.
