Abstract: A novel liquid crystal display device without a decrease in display quality. The liquid crystal display device includes a pixel for displaying a still image at a frame frequency of less than or equal to 1 Hz, and a liquid crystal layer in the pixel has a dielectric constant anisotropy of greater than or equal to 2 and less than or equal to 5. With the above 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 still image. Thus, flickers due to a low refresh rate can be reduced, which leads to an increase in display quality.

Abstract: The occurrence of a defective orientation of a polymer/liquid crystal composite is suppressed. In addition, the occurrence of defective display of a liquid crystal display device including the polymer/liquid crystal composite is suppressed. In the polymer/liquid crystal composite exhibiting a blue phase, a plurality of domains are included and defective orientations easily occur at boundaries between the domains. Thus, by lowering orientation periodicities at boundaries between the domains, a defect-free orientation to high orientation periodicities at the boundary between adjacent domains can be obtained. Specifically, the polymer/liquid crystal composite exhibiting the blue phase includes the plurality of domains each of which has a size of 3 μm or less.
