Abstract:
1. An image display device, comprising: a display panel a first substrate over the display panel; a plurality of first electrodes on the first substrate; a plurality of second electrodes alternately arranged with the plurality of first electrodes; a first alignment layer on the first and second electrodes; a second substrate facing the first substrate; a replica layer on the second substrate and having a concave pattern of half-cylinder shapes, the concave pattern facing the second electrode; a second alignment layer on the concave pattern, the second alignment layer corresponding to ends of the concave pattern contacts the first alignment layer to form a closed space; and a liquid crystal layer in the closed space and comprising liquid crystal molecules, wherein: wherein the liquid crystal layer includes liquid crystal molecules having positive refractive index anisotropy such that the replica layer has a refractive index being substantially same as an ordinary refractive index of the liquid crystal molecules wherein each of the plurality of first electrodes and the plurality of second electrodes has a bar shape, and a major axis of the bar shape is parallel to a major axis of the half-cylinder shape of the concave pattern, and wherein the liquid crystal molecules are aligned such that a major axis of the liquid crystal molecules is parallel to the first and second substrates and the major axis of the first electrodes, the second electrodes, and the half-cylinder shape in an OFF state.
