Abstract: A method for forming a display device includes forming a liquid crystal layer between a first substrate and a second substrate spaced apart from the first substrate, in which the liquid crystal layer includes a liquid crystal composition including a reactive mesogen, applying an electric field to the liquid crystal layer, firstly curing the liquid crystal layer at a temperature from about ?20° C. to about 60° C., and secondly curing the liquid crystal layer without applying the electric field. The liquid crystal composition includes the reactive mesogen in an amount exceeding 0 percent by weight and equal to or smaller than about 30 percent by weight relative to a total weight of the liquid crystal composition.

Abstract: 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.
