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.
Claims19
A liquid crystal display comprising:
- a first base substrate;
- a second base substrate facing the first base substrate;
- a liquid crystal layer disposed between the first base substrate and the second base substrate;
- a non-transmissive layer on the first base substrate and including concave-convex portions on a surface of the non-transmissive layer, wherein an upper surface of each of the convex portions is curved;
- a plurality of color filter layers including a cholesteric liquid crystal, the color filter layers being arranged on the non-transmissive layer;
- an alignment layer between the non-transmissive layer and the color filter layers;
- a first electrode on the color filter layers;
- and
- a second electrode on the second base substrate, wherein the first electrode includes a concave-convex structure corresponding to the concave-convex portions of the non-transmissive layer.
A color filter substrate comprising:
- a base substrate;
- a non-transmissive layer on the base substrate and including concave-convex portions on a surface of the non-transmissive layer, wherein an upper surface of each of the convex portions is curved;
- a plurality of color filter layers including a cholesteric liquid crystal,
- the color filter layers being arranged on the non-transmissive layer, wherein an electrode is formed on the color filter layers;
- and
- an alignment layer between the non-transmissive layer and the color filter layers, wherein the electrode includes a concave-convex structure corresponding to the concave-convex portions of the non-transmissive layer.
