摘要： A liquid crystal display includes a plurality of pixels, a first substrate, a second substrate, and a liquid crystal layer disposed between the first and second substrates. The first substrate includes a first base substrate and a pixel electrode provided on the first base substrate to correspond to each of the pixels. The second substrate includes a second base substrate facing the first base substrate and a common electrode provided on the second base substrate. The common electrode forms an electric field having an equipotential surface substantially parallel to an upper surface of the first base substrate in cooperation with the pixel electrode. The liquid crystal layer is disposed between the pixel electrode and the common electrode and includes a liquid crystal composition having an anisotropic dielectric constant equal to or smaller than −2.9 and equal to or larger than −1.7.

摘要： A display panel includes a first substrate and a second substrate facing the first substrate. The second substrate includes a first electrode and a second electrode spaced apart from each other. A cholesteric liquid crystal having a pitch shorter than a wavelength of a visible ray and a rotation axis substantially perpendicular to the first and second substrates is disposed between the first and second substrates. The display panel displays a grayscale image in response to an electric field generated between the first and second electrodes. A polymer is added to the cholesteric liquid crystal, and a concentration of the polymer is controlled by exposing the polymer to a light. The concentration of the polymer in an area adjacent to the first substrate may be higher than the concentration of the polymer in an area adjacent to the second substrate.
