Abstract: The present invention relates to a prism protection sheet with improved brightness used in a flat display such as a liquid crystal display or a light emitting diode, and the prism protection sheet has a feature of having 100 wt% or 130 wt% of the binder amount in a surface protection layer and includes a protection layer obtained from a composition which includes the binder and particles in both material film surfaces of the protection sheet. The prism protection sheet improves the brightness and maintains the protective function and processability of the surface with an optical condition by controlling the binder amount and the particle amount with a specific rate in one protection layer of the prism. In addition, the prism protection sheet improves the particle dispersibility using binders which are more than the particle amount in order to improve the brightness of a light vertically passing through the prism sheet by minimizing the size of the covered particles.

CONSTITUTION: The anti-reflection film is manufactured by filming the hardcoating layer(32) on the base film(10) for anti-reflection. The thickness of the hardcoating layer spreaded on the base film is 2.0 - 3.0μm. The photoinitiator content of the hard coating liquid used in the hardcoating layer coating is 1.0 - 2.5 weight%. The photoinitiator is a combination of one or more than one selected from the Acryl resin, urethane resin, melamine resin, organosilicate compound, silicone resin.
