Aspects of the invention provide an electro-optical device including first pixel portions each including an active element and second pixel portions each not including any active element, the first and second pixel portions being provided in an image display region of a substrate, a first driving device for driving the first pixel portions in an active driving method and a second driving device for driving the second pixel portions in a passive driving method. Accordingly, the invention can realize a display by using both an active driving method and a passive driving method with a simple structure.
