Abstract:
1. An LCD device, comprising: first and second substrates facing each other; a liquid crystal layer between the first and second substrates; first alignment layers on the first and second substrates; and a CDR (continuous director rotation) mode liquid crystal-based second alignment layer on at least one of the first and second substrates, wherein the CDR mode liquid crystal continuously rotates like a cone form based upon an applied electric field, a range of the rotation angle of the CDR mode liquid crystal is about 0° through 45° and the CDR mode liquid crystal is driven substantially on a surface while rotating around the cone, wherein the second alignment layer includes a main chain formed on the first alignment layer and a side chain branched from the main chain and combined with the CDR mode liquid crystal, wherein the second alignment layer is photo-cured during an initial alignment to form a polymer network, wherein the side chain moves on a plane substantially parallel to a surface of the second alignment layer, wherein the CDR mode liquid crystal is initially aligned on the second alignment layer substantially parallel to the substrate, wherein the CDR mode liquid crystal is adjacent to the liquid crystal layer and induces the liquid crystal layer to be driven on a surface, wherein a terminal group of the CDR mode liquid crystal is combined with the side chain, wherein the CDR mode liquid crystal continuously rotates on the terminal group.
