Abstract
Display devices with reduced power consumption are disclosed. In one example, a display device includes pixel circuits respectively connected to data lines in a first direction, a first voltage output unit that generates a first ramp wave voltage whose voltage level changes with time, and a first ramp wiring that supplies the first ramp wave voltage generated by the first voltage output unit to each of a plurality of data lines of a first group, in which at least two data lines of the plurality of data lines are brought into a conductive state before outputting the first ramp wave voltage to the first ramp wiring.
