Abstract:
Disclosed herein is a display device including: a pixel array unit having pixel circuits arranged in a form of a matrix; and a control unit having a writing scanning unit for outputting, to the sampling transistor, a writing scanning pulse. The control unit effects control to supply a control input terminal of the drive transistor with a fixed potential for a threshold value correcting operation for retaining a voltage corresponding to a threshold voltage of the drive transistor in the storage capacitor. When setting a voltage across the storage capacitor to the threshold voltage of the drive transistor by repeating the threshold value correcting operation a plurality of times on a time division basis, the control unit effects control to perform each the threshold value correcting operation and the sampling transistor to a conducting state.
