Abstract

A liquid crystal display includes a first base substrate, a second base substrate facing the first base substrate, a liquid crystal layer disposed between the first substrate and the second substrate, a non-transmissive layer on the first base substrate to absorb light, a plurality of color filter layers arranged on the non-transmissive layer and including a cholesteric liquid crystal to change a wavelength of light and reflect the light, an alignment layer arranged between the non-transmissive layer and the color filter layers to align the cholesteric liquid crystal, a first electrode on the color filter layers, and a second electrode on the second base substrate.
