Abstract
A display device capable of improving image quality is provided. A storage node is provided in each pixel and first data can be held in the storage node. Second data is added to the first data by capacitive coupling, which can be supplied to a display element. Thus, the display device can display a corrected image. A reference potential for the capacitive coupling operation is supplied from a power supply line or the like, and thus the first data and the second data can be supplied from a common signal line.
