Abstract: The invention provides a low-power consumption display device. The display device 10 is provided with a plurality of pixels P11˜Pnm arranged in a matrix formed by columns and rows, and a plurality of signal lines 16-1˜16-m arranged corresponding to every pixel rows or pixel columns. The display device further comprises a signal voltage generating part 12 electrically connected to the plurality of pixels P11˜Pnm via the plurality of signal lines 16-1˜16-m and generating signal voltages which are applied to the plurality of signal lines 16-1˜16-m, and a signal voltage amplifying part 14 amplifying the signal voltage generated by the signal voltage generating part 12 to a necessary drive voltage for each of the plurality of pixels P11˜Pnm.
