摘要： Power consumption of a display device is reduced. The display quality of the display device is improved. Video with high display quality is displayed regardless of the usage environment. The display device includes a first pixel performing display with reflected light, a second pixel including a light source and performing display with light from the light source, a driver portion driving the first pixel and the second pixel, a photometric portion measuring and outputting illuminance of the external light, and a control portion generating a first gray level output to the first pixel and a second gray level output to the second pixel on the basis of information of the illuminance input from the photometric portion and outputting the first and second gray levels to the driver portion. In addition, the control portion generates the first and second gray levels so that the first gray level is the largest among the combinations of the first and second gray levels at which chromaticity and luminance of light obtained by adding light output from the first pixel and light output from the second pixel have predetermined values.

摘要： Provided is a novel liquid crystal display device without deterioration of display quality. The liquid crystal display device includes a pixel for displaying a still image with a frame frequency of 1 Hz or lower. The pixel includes a liquid crystal element which includes a liquid crystal layer and has a cell gap of d (μm). The liquid crystal layer includes a liquid crystal composition which includes a liquid crystal material. The helical pitch of the liquid crystal material is longer than or equal to 4d μm and shorter than or equal to 8d μm. With this structure, a change in voltage applied to a pixel can be kept within an acceptable range of a deviation in gray level for displaying the same image. Thus, flickers due to a low refresh rate can be reduced, which leads to an increase in display quality.
