CHOLESTERIC LIQUID CRYSTAL LAMINATES PRODUCING METHOD FOR PRODUCING SAME AND COMBINATION OF CHOLESTERIC LIQUID CRYSTAL LAMINATES

摘要

At least one light reflecting layer Xa containing a chiral agent having a preferential rotation having HTP of 30 占 퐉 ^-1 or more and a light reflecting layer comprising a cholesteric liquid crystal phase immobilized thereon , And at least one light reflecting layer Xb containing a left-handed chiral agent having an HTP of 30 탆 ^-1 or more, and the selective reflection wavelength of all the light reflecting layers Xa and all the light reflecting layers Xb is in the range of 400 nm to 750 nm And the light reflection layers formed by fixing all of the adjacent cholesteric liquid crystal phases to each other are arranged such that the selective reflection wavelength of the at least one light reflection layer Xa and the selective reflection wavelength of the at least one light reflection layer Xb are equal to each other, The cholesteric liquid crystal laminate in contact with each other is a laminate in which right and left reversely twisted cholesteric liquid crystal layers are laminated in contact with each other without using an adhesive material, And, high transparency, and has a selective reflection characteristic in the visible light region, there is a high reflection performance.
