Abstract
The present invention relates to a composition for manufacturing optical elements with negative optical dispersion, and an optically anisotropic body prepared therefrom. According to the present invention, the optically anisotropic body showing stable reverse wavelength dispersion can be prepared more simply by using the composition for optical elements, and it is possible to apply the same to liquid crystal display devices as an optical film such as a thin-layer broadband λ/4 plate.
