Abstract
The disclosure provides for a phase compensation film that includes nano-particles of a cross-linked polymer with a largest dimension of a quarter of a wavelength of visible light or less, and a liquid crystal substance imbibed substantially throughout the cross-linked polymer of the nano-particles to provide a phase compensation value for a pixel of a liquid crystal display.
Claims22
A phase compensation film, comprising:
- a particle having a cross-linked polymer domain with a largest dimension of 5 nm to 175 nm;
- and
- a liquid crystal substance imbibed substantially throughout the cross-linked polymer domain of the particle to provide a phase compensation value for the phase composition film.
A film forming composition, comprising:
- a particle having a cross-linked polymer domain with a largest dimension of 5 nm to 175 nm;
- a liquid crystal substance imbibed substantially throughout the cross-linked polymer domain of the particle;
- and
- a liquid medium, where the liquid medium suspends the particle having the liquid crystal substance substantially throughout the cross-linked polymer domain of the particle.

A method of forming a phase compensation film, comprising:
- applying a film forming composition to a substrate, where the film forming composition includes:
- particles each having a cross-linked polymer domain with a largest dimension of 5 nm to 175 nm;
- a liquid crystal substance imbibed substantially throughout the cross-linked polymer domain of the particles to provide a phase compensation value for the phase compensation film;
- and
- a liquid medium, where the liquid medium suspends the particles imbibed therein with the liquid crystal substance.
