Title:
化合物、光学フィルム及び光学フィルムの製造方法
Document Type and Number:
Japanese Patent JP6744962
Kind Code:
B2
Abstract:
To provide an optical film capable of uniform polarization conversion in a broader wavelength range.SOLUTION: A composition for an optical film includes a cyclopentanone or cyclohexanone, and a compound containing a group expressed by an expression (A) and a polymerizable group: -Ga-Da-Ara-Db-Gb-(A). An optical film 2 can be formed by applying on an orientation film 3 and polymerizing by ultraviolet light irradiation, therefore an optical film with a broad band, for instance, λ/4, λ/2, can be formed on a color filter 1 more easily than conventionally done.SELECTED DRAWING: Figure 1
