Document Type and Number:
WIPO Patent Application WO/2017/216886
Kind Code:
A1
Abstract:
A polarizing film with double-sided adhesive layers according to the present invention includes a polarizing film arranged nearest a viewing side on an image display device, an adhesive layer A arranged on the viewing side of the polarizing film, and an adhesive layer B arranged opposite the adhesive layer A. The adhesive layer A is provided with a separator SA and the adhesive layer B is provided with a separator SB. The polarizing film is a one-side protected polarizing film where a transparent protective film is provided only on one side of the polarizer having a thickness of 15 μm or less. The adhesive layer B is arranged on the transparent protective film. The adhesive layer A has a thickness of 25 μm or greater, and the adhesive layer B has a thickness of 25 μm or less. The polarizing film with double-sided adhesive layers can facilitate thinning by using the one-side protected polarizing film as the polarizing film while suppressing the occurrence of curling and improving re-workability.
