RETARDATION FILM, COMPOSITION, METHOD OF MANUFACTURING RETARDATION FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
An object of the present invention is to provide a film capable of giving a necessary retardation without degrading the contrast. The present invention provides a retardation film formed from a composition which includes a polymer compound, a rod-like liquid crystal compound and a photo-reactive compound, wherein the polymer compound has a side chain which has one or more azo groups and/or cynnamate groups, and 3 or more and 10 or less arylene groups; the side chain further has an optionally substituted amino group, or a hydrocarbon group at the terminal; an absolute value of difference between an SP value of the polymer compound and an SP value of the photo-reactive compound is 1.1 or less; and an in-plane retardation of the film at wavelength of 550 nm is 10 nm or more and 200 nm or less. |

1. A retardation film formed from a composition which comprises a polymer compound, a rod-like liquid crystal compound and a photo-reactive compound, wherein the polymer compound has a side chain which has one or more azo groups and/or cynnamate groups, and 3 or more and 10 or less arylene groups; the side chain further has an optionally substituted amino group, or a hydrocarbon group at the terminal; an absolute value of difference between an SP value of the polymer compound and an SP value of the photo-reactive compound is 1.1 or less; and an in-plane retardation of the film at wavelength of 550 nm is 10 nm or more and 200 nm or less. |
