A method is disclosed for controlling a pretilt angle direction for a liquid crystal cell comprising the steps of first setting the magnitude of pretilt angle and a plurality of pretilt angle directions in an alignment layer. This first step is achieved by irradiating linearly the alignment layer with polarized or unpolarized UV light. One of the plurality of pretilt angle directions is then selected by exposing the alignment layer to UV light a second time.

Method for controlling pretilt angle direction in a liquid crystal cell

A method for fabricating a multi-domain liquid crystal cell is disclosed, wherein first and second alignment directions are formed in first and second portions of an alignment layer provided on a substrate by selectively subjecting the first and second portions to different energy doses of linearly polarized ultraviolet light. Liquid crystal material is then injected between the one substrate and another substrate and into contact with the alignment layer, thereby obtaining a wide viewing angle in the liquid crystal device.

Method for manufacturing a multi-domain liquid crystal cell

A method for manufacturing a multidomain liquid crystal display panel, including the steps of forming a photo-alignment layer on a substrate, positioning a mask having a plurality of regions with different photo-transmittances; and forming different alignment directions in different domains of the photo-alignment layer corresponding to each of the plurality of regions by irradiating the photo-alignment layer with light through the mask.
