Original Abstract Submitted
Display devices that retain display quality under ramp wave voltage pixel driving are disclosed. In one example, a display device includes signal lines that supply signal voltages corresponding to gradation to pixel circuits. An error amplifier outputs an instruction signal corresponding to a difference between first and second ramp wave voltages. The second ramp wave voltage is output in response to the instruction signal. Voltage holding units hold the second ramp wave voltage and generate the signal voltages at a timing according to luminance of the pixel circuits by switches connected between ramp wiring and the signal lines. Correction current sources supply a correction current to connection paths between the ramp wiring and the voltage holding units, and a current adjustment unit adjusts the correction current on the basis of the instruction signal.
