Vertical aligned liquid crystal display and method using dry deposited alignment layer films

A method for producing a liquid crystal display device, comprising:

• depositing an alignment film on first and second substrates by one of physical and chemical vapor deposition;
• and
• providing a liquid crystal material adjacent to said alignment film,
• wherein said alignment film as deposited allows a truly vertical alignment of molecules of said liquid crystal material such that said molecules form an angle of substantially 90° relative to the substrate.

A liquid crystal display device, comprising:

• a first substrate;
• an alignment film deposited over said first substrate by one of physical and chemical vapor deposition and ion beam treated;
• a second substrate coupled to said first substrate with said alignment film deposited over said second substrate and then ion beam treated therebetween and forming a cell gap;
• and
• a liquid crystal material formed in said cell gap, said alignment film allowing a tilted vertical alignment of molecules of said liquid crystal material such that said molecules have a pretilt angle of 0.5 to 10 degrees from a substrate normal direction.

A method of forming a liquid crystal device comprising:

• depositing, on at least one substrate, an a alignment film by one of physical and chemical vapor deposition;
• treating said alignment film with an ion beam;
• and
• providing a liquid crystal material adjacent to said alignment film, said liquid crystal material having a tilted vertical alignment having an angle of substantially 0.5 to 10° relative to the substrate normal.
