Abstract:
1. A method for manufacturing liquid crystal display elements comprising the steps of: forming polarized light from non-polarized light by the use of a polarizer having a grating and an integrator lens; uniformizing a polarization axis of the polarized light with respect to an irradiation region by adjusting an incident angle of the non-polarized light to the grating by the use of the polarized light obtained at a plurality of measurement positions through a polarization axis monitor; uniformizing an intensity of the polarized light irradiated from the integrator lens with respect to the irradiation region by adjusting an optical axis of the integrator lens using the intensity of the polarized light obtained at a plurality of measurement positions through the polarization axis monitor; and collectively irradiating an alignment film with the polarized light having the uniformized polarization axis and light intensity, thereby aligning the alignment film.
