Abstract
According to one embodiment, a display device includes a display panel including a display area where first drive areas and second drive areas are alternately disposed, and display function layers which include first display function layers and second display function layers and which are changed to a transparent state and a scattering state, and a control unit. The control unit applies a drive voltage to the first display function layers, in a first field period. The control unit applies the drive voltage to the second display function layers, in a second field period. A polarity of the drive voltage in the first field period is different from a polarity of the drive voltage in the second field period.
