OPTICAL SHEET WITH ELASTICITY

摘要

An optical sheet with elasticity including a structural layer made of resin hardening layer is provided to maintain a function of a prism structure by preventing brightness deterioration due to a difference of an optical path. An optical sheet with elasticity comprises a structural layer(10) and a plane penetrator(11). The structural layer is a resin hardening layer in which a surface is structured. The plane penetrator uses on a structured surface. The optical sheet pressurizes until a maximum pressure is 1gf or 2gf at a pressure speed of 0.2031mN/sec. When reaching the maximum pressure, the optical sheet stops for 5 second and compresses. The optical sheet has a resilience rate of 85% or greater.
