Abstract
A display apparatus is provided in which at least one pixel electrode in a plurality of pixels overlaps with a data line among a plurality of data lines. A data signal may be supplied to each of the plurality of pixels via the plurality of data lines once per one frame, and an initializing voltage is supplied to the pixel electrode in each of the plurality of pixels at least twice per one frame. A time taken for the data signal to be supplied to each of the plurality of pixels during one frame is less than or equal to a period during which the initializing voltage is supplied to the pixel electrode in each of the plurality of pixels during one frame.
