ABSTRACT:
A display apparatus is arranged such that each of a plurality of pixels formed on a display area has, for instance, an organic EL device as a display device, and each of the organic EL devices has a voltage variation section which can change the value of a display voltage supplied to each of the organic EL devices. Moreover, the display apparatus preferably includes voltage keeping sections for keeping the input voltage of the voltage variation sections and storage sections for storing image data. On this account, it is possible to further reduce the power consumption of the display apparatus and downsize the display apparatus as display means, so that the display apparatus can be suitably adopted as display means of a mobile device.
