Abstract:
1. A method of manufacturing a display panel, comprising: forming a cholesteric liquid crystal between a first substrate and a second substrate, wherein the second substrate includes first and second electrodes spaced apart from each other, and the cholesteric liquid crystal has a pitch shorter than a wavelength of a visible ray and a rotation axis substantially perpendicular to the first and second substrates; generating an electric field between the first and second electrodes; adding a polymer to the cholesteric liquid crystal; and controlling a concentration of the polymer in the cholesteric liquid crystal by exposing the polymer to a light, wherein the light is transmitted through the first substrate and is incident to the second substrate, and the concentration of the polymer is lower in an area adjacent to and extending along the second substrate than the concentration of the polymer in an area adjacent to and extending along the first substrate.
