Abstract
It is an object of the present invention to provide an apparatus and a method for forming an alignment layer to align the orientation direction of liquid crystals. In an apparatus 10 for forming an alignment layer according to the present invention, the shape of an edge 32a of a mask 12 for forming a slit 14 is determined by integrating the orientation direction of liquid crystals. The liquid crystals can be uniformly oriented by the edge 32a having such shape. This leads to the manufacturing of a liquid crystal display free from irregularity in brightness and color.
Claims10
-12. (canceled)
A method for forming an alignment layer on a substrate of a liquid crystal display, comprising:
- projecting an ion beam on an edge of a mask so that said edge is projected onto the substrate;
- moving the substrate in a predetermined direction;
- and
- integrating an orientation direction of liquid crystals in the liquid crystal display to determine a shape of said edge as projected on the substrate.
A method for forming an alignment layer on a substrate of a liquid crystal display, comprising:
- utilizing a generating source to generate an ion beam;
- interdisposing a plurality of masks between the substrate and said generating source such that a first edge of a first one of said plurality of masks and a second edge of a second one of said plurality of masks forms a slit;
- projecting said ion beam through said slit;
- moving the substrate in a predetermined direction such that said ion beam irradiates a film on the substrate;
- and
- determining the shape of said first or second edge based on the orientation direction of liquid crystals contained in the liquid crystal display.
