摘要： A display device includes a display unit, a horizontal drive circuit, and a vertical drive circuit, the display unit including pixels in a matrix formation, as well as respective signal lines and scan lines via which the drive circuits drive the pixels. Each pixel includes a light-emitting element, a hold capacitor, a write transistor, and a drive transistor. Mobility fluctuations in the drive transistor are compensated for by successively setting the voltage of the signal line to an intermediate voltage and to a tone voltage. In addition, the intermediate voltage is varied in accordance with the tone voltage as well as with the distance from the input terminal of a write signal to a respective pixel. The device thereby compensates for mobility fluctuations in the drive transistor and prevents shading due to irregularities in the waveform of the write signal.
