Abstract
In a method and apparatus of aligning liquid crystal, a first ion beam is formed. The first ion beam is transformed into a second ion beam having transformed cross-section. The second ion beam advances toward a thin film including carbon-carbon double bond. The second ion beam forms a first angle with respect to the thin film. The second ion beam is transformed into an atomic beam. The atomic beam is irradiated onto the thin film to break the carbon-carbon double bond. The carbon-carbon double bond is broken to form a polarized functional group for aligning a liquid crystal molecule.

A method of aligning liquid crystal, comprising:
- forming a first ion beam;
- transforming the first ion beam into a second ion beam having a transformed cross-section, the second ion beam advancing toward a thin film including a carbon-carbon double bond, the second ion beam forming a first angle with respect to the thin film;
- transforming the second ion beam into an atomic beam;
- and
- irradiating the atomic beam onto the thin film to break the carbon-carbon double bond to form a polarized functional group for aligning a liquid crystal molecule.
An apparatus for aligning a liquid crystal molecule, comprising:
- a first ion beam generating part for generating a first ion beam;
- a second ion beam generating part for transforming the first ion beam into a second ion beam having a transformed cross-section, the second ion beam advancing toward a thin film including carbon-carbon double bond, the second ion beam forming a first angle with respect to the thin film;
- an atomic beam generating part for transforming the second ion beam into an atomic beam;
- and
- a transferring part for changing a relative position between the atomic beam generating part and the thin film, the atomic beam being irradiated onto the substrate so as to break the carbon-carbon double bond of the substrate while the atomic beam generating unit scanning the thin film, thereby forming a polarized functional group for aligning the liquid crystal molecule in the thin film.
