Optically transmitting sheet and screen

摘要

Disclosed are a light transmission sheet and a screen that can realize good color reproduction while suppressing a lowering in light transmittance. The light transmission sheet comprises a light diffusing sheet and/or a colored sheet. The light diffusing sheet and/or the colored sheet comprise light diffusing fine particles dispersed in a light transparent matrix and satisfy formula (1): <?in-line-formulae description="In-line Formulae" end="lead"?>-0.5%<=T1-T2<=5% (1)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein T1 represents light transmittance at a wavelength of 450 nm, %; and T2 represents light transmittance at a wavelength of 600 nm, %. A light diffusing sheet and/or colored sheet for a screen are also disclosed. The screen comprises the light diffusing sheet and/or colored sheet for a screen.
