Abstract:
1. A panel comprising: first and second films disposed opposite each other; a polymer layer interposed between the first and second films, the polymer layer formed of a polymer having light alignment and light-curing characteristics, the polymer layer in which the polymer is arranged in one direction; and a plurality of liquid crystal (LC) droplets dispersed in the polymer layer, wherein when a voltage is not applied across the polymer layer, each of the plurality of LC droplets includes a plurality of LC molecules, which are arranged in the same direction as the direction in which the polymer layer is arranged, and the panel transmits light, and wherein when a voltage is applied across the polymer layer, the polymer layer with the plurality of LC droplets has a phase retardation of λ/2, and the panel changes light transmitted through a polarizer into a left-linearly polarized light state or right-linearly polarized light state.
