Abstract
This invention relates to a complex prism sheet which is configured such that heat-resistant coating layers are formed on both surfaces of a substrate layer, thus preventing wrinkling or curling of the complex prism sheet due to heat generated from a light source, and increasing concealment and electro-optic characteristics, ultimately improving properties of a light crystal display. This complex prism sheet can be usefully applied to television (TV) sets, monitors, notebook personal computers (NBPCs), etc., which are required to have heat resistance, slimness and concealment because of an increasing use of a light emitting diode (LED) light source these days.
