Abstract
To provide a light-emitting device capable of suppressing the display of an afterimage. A plurality of pixels arranged in n rows and m columns (n and m are each an integer of 2 or more) is supplied with a first signal containing image data and a second signal for initializing the pixels. Each pixel includes a first transistor for controlling the input of the first signal and a second transistor for controlling the input of the second signal. The first transistor in a k-th row (k is an integer of 1 to n) and the second transistor in a k+1-th row are turned on at the same time, so that the pixels are initialized and display images effectively.
