A display device, and method of driving the same, enabling stable and accurate supply of a current having a desired value to the light emitting element of each pixel without regard not only to variation of the threshold values of the active elements inside the pixels, but also to variation of the mobilities and enabling display of a high quality image as a result, wherein a current transfer circuit samples and holds a reference current of a reference current supply line for a time of 20 H by turning on TFTs as fifth and sixth switchs before an auto-zero operation in pixel circuits in pixel units, and after an elapse of a 20 H period, outputs and transfers the sampled and held reference current Iref to the reference current transfer line by holding a TFT as a seventh switch in the on state for the period of 20 H after the TFTs as fifth and sixth switchs are turned off. The pixel circuits sequentially fetch the reference current Iref transferred to the reference current transfer line for the period of 1 H and perform the auto-zero operation.
