Abstract
A display device having a novel structure that can improve reliability is provided. It lowers reliability to form a structure by using a photomask, such as a color filter on a rear side of a substrate. With this display device, a transistor and the color filter is provided over a first substrate, a touch sensor is provided on a first surface of a second substrate, and the structure is not provided on a second surface of the second substrate. Consequently, the display device with the touch sensor can perform high reliability.
