The invention discloses a pixel circuit and a displayer. According to the pixel circuit, the size of the pixel circuit is reduced, so that the distance between every pixels is reduced, the number of the pixels contained in unit area is increased, and the display quality of an image is improved. The pixel circuit comprises a first pixel sub circuit, a second pixel sub circuit, an initializing module and a data voltage write-in module, wherein the initializing module and the data voltage write-in module are connected with the first pixel sub circuit and the second pixel sub circuit. The initializing module is connected with a reset signal end and a low potential end and used for initializing the first pixel sub circuit and the second pixel sub circuit under the control of a reset signal input by the reset signal end. The data voltage write-in module is connected with data voltage and a gate signal end and used for writing first data voltage in the first pixel sub circuit under the control of a signal input by the gate signal end, compensating a driving module of the first pixel sub circuit, writing second data voltage in the second pixel sub circuit and compensating a driving module of the second pixel sub circuit.
