Abstract: An integrated light guide panel for use in a backlight unit for an LCD and a method for manu¬ facturing the same are disclosed. The integrated light guide panel includes a light guide panel for guiding light, to form surface light, a reflective coating layer arranged beneath the light guide panel, to reflect light emerging from a lower surface of the light guide panel such that the light is again incident to the light guide panel, a diffusive coating layer arranged over the light guide panel, to diffuse light emerging from the light guide panel, a prism coating layer arranged over the diffusive coating layer, to concentrate light emerging from the diffusive coating layer, and low refractive coating layers respectively arranged between the light guide panel and the reflective coating layer and between the light guide panel and the diffusive coating layer. In accordance with this configuration, it is possible to reduce the number of assembly processes for the backlight unit, and thus to achieve improvements in workability and quality. It is also possible to prevent the generation of blemishes caused by wrinkles in optical films.

Abstract: A prism sheet having a concave pentagonal structure is disclosed. The prism sheet comprises a base layer, and a prism array disposed on and supported by the base layer. The prism array is composed of a plurality of prisms aligned in parallel and one beside the other. The transversal cross-section of each prism has a shape of concave pentagon, which is symmetrical about a vertical line passing the apex. The interior angle α of the apex is 30° ≤ α ≤ 120°, the exterior angle ß formed by the upper slant side and the lower slant side is ß ° and the length w of the base is 30µm ≤ w ≤ 100µm. Preferably, the interior angle α of the apex may be 40° ≤ α ≤ 100 ° , the exterior angle ß formed by the upper slant side and the lower slant side may be 160° ≤ ß ≤ 179 ° , and the interior angle y of the lower vertex formed by the lower slant side and the base may be 30 ° ≤ y ≤ 60°. Preferably, the length w of the base may be 40µm ≤ w ≤ 60µm.
