UNIFIED OPTICAL SHEET

摘要

PURPOSE: An integrated optical sheet is provided to shorten an assembling process by omitting a separate bonding process or a mounting process on a lateral rack. CONSTITUTION: A first optical sheet(20) includes a first optical functional body. A reflective polarization sheet(10) is arranged on the upper part of the first optical sheet. A bonding layer(40) combines the first optical sheet and the reflective polarization sheet. The reflective polarization sheet is comprised of cholesteric liquid crystals.
