The present invention provides a polarized-light irradiation device and a method for manufacturing a liquid crystal display device which uses the polarized-light irradiation device, whereby the alignment azimuth angle Theta of liquid crystal molecules can be set to a desired angle even when the incidence angle of polarized light on a substrate is not 0 degree when polarized light is radiated to aphotoalignment film. This polarized-light irradiation device is used in alignment processing of a photoalignment film provided on a substrate (10), and is provided with a stage (250) having a mountingsurface (251) on which the substrate (10) is mounted, and a polarized-light irradiation part (260) for radiating polarized light toward the mounting surface (251) via a polarizer (210) from a direction inclined with respect to a line normal to the mounting surface (251), the polarized-light azimuth angle alfa, which is the angle of the polarization axis of the polarizer (210) when the polarization axis of the polarizer (2
