Abstract:
The present invention provides a luminance enhancement film which is superior in dimensional stability, thermal stability, and anti-deformation ability. Thus, it can meet the current requirement for thinning LCD apparatuses.With regard to the luminance enhancement film, a prism row structure is formed on a surface of a substrate, and a reinforced layer is formed on the other surface of the substrate. The glass transition temperature of the reinforced layer is in the range from 80° C. to 250° C., and the thickness of that is in the range from 3 μm to 50 μm.
