Document Type and Number:
Japanese Patent JP2010026029
Kind Code:
A
Abstract:
To provide an optical film having new composition exhibiting the wavelength dispersion characteristics such that as a wavelength at least in the visible light range becomes shorter, a birefringence becomes smaller (reverse wavelength dispersion characteristics).
This optical film includes a layer formed of a resin (A) having a molecular structure shown in formula (1). In the formula (1), n is a natural number of 1-4, R1 and R2 is each independently a hydrogen atom or a methyl group.
