Document Type and Number:
Japanese Patent JP7273985
Kind Code:
B2
Abstract:
The present invention provides: an optically anisotropic film having greater refractive index anisotropy and exhibiting reverse wavelength dispersibility; a polarizing plate; an image display device; a composition; and a compound. The optically anisotropic film of the present invention is formed by using a composition containing a compound represented by formula (1) and exhibits reverse wavelength dispersibility. Formula (1) (X)p-D D represents a dye skeleton having a maximum absorption wavelength in the wavelength range of 700-900 nm. X represents a group represented by formula (2) and having a maximum absorption wavelength in the wavelength range of 280-400 nm. p represents an integer of at least 1. Formula (2) Y-SP-(AZ)n-*
