Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A liquid crystal display device comprising a plurality of pixels,
wherein one pixel of the plurality of pixels comprises a first sub pixel and a second sub pixel, which are adjacent to each other,
wherein the one pixel comprises:
a first substrate;
a first electrode on the first substrate;
metamaterial layers on the first electrode, wherein the metamaterial layers comprise a first metamaterial layer within the first sub pixel and a second metamaterial layer within the second sub pixel;
a liquid crystal layer on the first and second metamaterial layers;
a second electrode on the liquid crystal layer; and
a second substrate on the second electrode,
wherein the first metamaterial layer and the second metamaterial layer comprise metamaterials having properties different from each other, respectively, and
wherein, under a first voltage applied to the first electrode,
the first metamaterial layer is configured to phase-modus a first port on of the liquid crystal layer to a first value.
