Abstract: A resin sheet, a manufacturing method for the same, and a liquid crystal display are provided to make the resin sheet thinner and lighter than a glass-based substrate and to secure anti-glare function of the resin sheet by forming an uneven hard coating layer at the outermost side. The resin sheet is composed of a gas cut-off layer(3), a base layer(2), and one hard coating layer(1) formed as an outermost layer and provided with an uneven part on the outer surface. The uneven surface has the surface roughness of 80~500nm and a peak-to-valley distance of 20~80nm. The base layer contains epoxy resin. The hard coating layer contains urethane resin. The uneven part is formed on the surface of the hard coating layer by transferring the shape of a recessed part formed on a base material.

Abstract: 다층 유전체반사기(160)에 있어서, 반사기의 표면을 선택적으로 처리하면 반사기를 통해 투과되는 빛의 양이 증가한다. 다양한 표면 처리를 이용하여 처리를 하지 않을 경우 반사될 빛이 반사기를 통해 투과하도록 할 수 있다. 그러한 한 반사기에서, 표면의 상이한 부분(101, 103, 107, 109)은 높은 전파각을 갖는 빛을 다층 반사기 안으로 커플링시키기 위해 다른 커플링 효율(101, 107)을 갖는다. 반사기의 각 면에 더 높은 커플링 효율을 갖는 그러한 부분들은 더 높은 투과도를 갖는다.
