Abstract:
1. An active matrix-type display device having a pixel circuit for each of a number of pixels arranged in matrix to control the light-emitting period, wherein, each pixel circuit includes: a light emitting element which emits light in response to a driving current, a driver element for controlling the driving current supplied to the light emitting element, a capacitance in which a signal voltage is written from a signal line for applying a voltage corresponding to the written signal voltage to the gate of the driver element, and a gate potential control line for shifting the potential of the capacitance to control the gate potential of the driver element, wherein, one frame is divided into a plurality of subframes, and in each of the subframes, at least three stages of signal voltage are written in the capacitance from the signal line, and in one subframe, after the signal voltage is written in, the subframe is further divided to form sub-subframes by changing the gate potential of the driver element by the gate potential control line for controlling the gate electrode voltage of the driver element in the sub-subframe by combining the signal voltage and the voltage of the gate potential control line to control a light emitting period of the light emitting element.
