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.

A light irradiating device for a photo-alignment process comprises an optical system and a first polarizer polarizing the light from the optical system. The light from the first polarizer is obliquely irradiated at an angle with respect to a normal direction of a stage on which a substrate is placed.
