Disclosed are a pixel circuit, a display panel and a display device. The pixel circuit includes driving circuits which are in one-to-one correspondence to data lines, each driving circuit being disposed in a peripheral area of a display panel; compensating circuits which are in one-to-one correspondence to gate lines, each compensating circuit being disposed in a peripheral area of the display panel; and light emitting devices. Each compensating circuit outputs a first reference signal or a second reference signal to the corresponding driving circuit. Each driving circuit drives a corresponding light emitting device to emit light through a signal from the corresponding compensating circuit and a data signal from the corresponding data line. The pixel circuit of the present disclosure can improve the aperture ratio of a pixel unit.
