Title:
NOVEL REACTIVE MESOGEN COMPOUND, COMPOSITION CONTAINING SAME FOR REVERSE-WAVELENGTH DISPERSION COMPENSATION FILM, AND REVERSE-WAVELENGTH DISPERSION COMPENSATION FILM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/054587
Kind Code:
A1
Abstract:
The present invention relates to a hydrogen bond mixture for a reverse-wavelength dispersion compensation film, the hydrogen bond mixture exhibiting a reverse-wavelength dispersion characteristic due to an self-assembly arrangement between host-guest reactive mesogens enabling hydrogen bonding, as a one-layer structure, and to a compensation film comprising the same. A film manufactured by the present invention is characterized in that the film induces more stable self-assembly between host-guest reactive mesogens due to an intermolecular host-guest interaction through hydrogen bonding, thereby having improved aligning properties and having a wavelength dispersion characteristic close to a more ideal value, as compared with an existing one-layer type reverse-wavelength dispersion compensation film. Therefore, the reverse-wavelength dispersion compensation film proposed in the present invention can be used for an anti-reflective function of an OLED or viewing angle compensation of an LCD. The reverse-wavelength dispersion compensation film of the present invention has advantages in that the thickness of an element can be reduced and the manufacturing process is simple, as compared with an existing stacked type reverse-wavelength dispersion compensation film.
