Abstract: A photo-irradiating apparatus includes a UV lamp generating the UV light, a lens, a polarizer in which the UV light is linearly polarized, and a substrate exposed by the linearly polarized UV light. The UV lamp, the lens, and the polarizer are arranged in a line. The UV light is irradiated into the alignment layer during the moving of a scan motor to irradiate the whole area of the alignment layer uniformly. In addition, the light is obliquely irradiated into the alignment layer so that the area exposed to the light is enlarged.

Abstract: 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.
