Claims26
An optical film comprising:
- a block copolymer that comprises a vinyl polymer block containing styrene or a derivative thereof, and a polydimethylsiloxane block.
(canceled)
A method of manufacturing an optical film, the method comprising the steps of:
- 1) preparing a block copolymer that comprises a vinyl polymer block containing styrene or a derivative thereof, and a polydimethylsiloxane block;
- and
- 2) forming a film by using the block copolymer.
(canceled)
A retardation film comprising:
- a block copolymer that comprises a vinyl polymer block containing styrene or a derivative thereof, and a polydimethylsiloxane block.
(canceled)
A method of manufacturing a retardation film, the method comprising the steps of:
- 1) preparing a block copolymer that comprises a vinyl polymer block containing styrene or a derivative thereof, and a polydimethylsiloxane block;
- and
- 2) forming a film by using the block copolymer;
- and
- 3) uniaxially or biaxially stretching the film.
(canceled)
An integrated polarizing plate comprising:
- a polarizing film;
- a retardation film that comprises a block copolymer that comprises a vinyl polymer block containing styrene or a derivative thereof, and a polydimethylsiloxane block on a side or both sides of the polarizing film as a protective film.
