A polymer which enables good wettability at the time of coating and does not cause sintering when added to a coating film forming composition, a composition containing the same, and a film formed using the composition are excellent in surface appearance, And a liquid crystal display device having the optical film. A polymer comprising two or more radically polymerizable double bonds and a monomer having at least one hydroxyl group, a composition comprising the polymer, and an optical film formed using the polymer, and a liquid crystal display device comprising the optical film. |
