Abstract: According to one embodiment, a first Pixel is connected to a first source line via a first switch included in a first Pixel and the second Pixel is connected to a second source line via a second switch included in the second Pixel. The first Pixel has a first memory, and the second Pixel has a second memory. A first potential line supplies data 1 and a second potential line supplies data 0. The first and second Pixels can store data 1 or 0, when a gate signal is applied to a gate line and the first and second switches are turned on. In this case, in order to store the same data (1 or 0) in the first and second memories, the first and second source lines should be applied different revel signals each other.
