Title:
COMPOSITION FOR WIDE-VIEWING ANGLE AND REVERSE-WAVELENGTH DISPERSIBILITY COMPENSATION FILM AND COMPENSATION FILM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2017/222291
Kind Code:
A2
Abstract:
The present invention relates to a composition for a wide-viewing angle and reverse-wavelength dispersibility compensation film, the compensation film having a one-layer structure and exhibiting wide viewing angle and reverse-wavelength dispersibility characteristics according to a self-assembly arrangement between polymerizable smectic reactive mesogens, and to a wide-viewing angle and reverse-wavelength dispersibility compensation film by the composition. The film manufactured by the present invention has excellent viewing angle characteristics compared with an existing one-layer type reverse-wavelength dispersibility compensation film, and can be used for an anti-reflective function of an OLED or viewing angle compensation of an LCD. The reverse-wavelength dispersibility compensation film of the present invention has advantages of reducing the thickness of a device and simplifying the manufacturing process compared with an existing stack type reverse-wavelength dispersibility compensation film.
