FORWARD SCATTERING SHEET, LAMINATED SHEET USING THE SAME AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a forward scattering sheet capable of giving higher brightness and contrast to a reflective or semi-transmissive and semi-reflective liquid crystal display device and to provide a laminated sheet using the forward scattering sheet and a liquid crystal display device. SOLUTION: The forward scattering sheet is obtained by forming a colorless transparent resin containing 1-100 pts.wt. dispersed colorless transparent spherical fine particles of 2-5 μm average particle diameter based on 100 pts.wt. resin in a sheet shape of 1-100 μm thickness and has 85-100% total light transmittance T and 50-90% haze rate Hz. The refractive index n(R) of the colorless transparent resin and the refractive index n(F) of the colorless transparent spherical fine particles satisfy the relation of 0.00
