Abstract

Provided is a novel display device without deterioration of display quality or a novel display device in which flickering due to a reduced refresh rate is suppressed. The display device includes a pixel for displaying a still image at a frame frequency of less than or equal to 1 Hz. The pixel includes a liquid crystal layer. The liquid crystal layer includes a molecule whose dipole moment is greater than or equal to 0 debye and less than or equal to 3 debye. Thus, flickering due to a reduced refresh rate can be suppressed, which leads to an improvement in display quality.
