Abstract
A display device is driven by a driving method including a first drawing step of displaying an image by controlling a display medium on the basis of a first image signal, and a second drawing step of overwriting a handwritten image on the displayed image by controlling the display medium on the basis of a second image signal. In the first drawing step, an image is drawn by a reset drive for resetting a previous display image and a writing drive for writing an image, and in the second drawing step, the writing drive of a minimum or a substantially maximum luminance is performed without effecting the reset drive only in an area in which the handwritten image is written.
