Abstract: In the display device according to the present disclosure, three segments have the same total areas which are sum of the area of the lower electrode and the area of the cover wiring, and response speeds of the three segments are the same when the drive current is supplied. Since there is no difference in response speeds to the drive current between the segments, even if luminance adjustment is performed by a pulse width modulation, the luminance difference between the segments does not occur.
