Problems solved by technology

[0021] As mentioned above, the mesh of the wire grid polarizing element is manufactured by fine processing, and the width or interval of the mesh is, for example, 100 nm. Therefore, if it is touched by a hand due to mishandling or an object is dropped on it, the mesh structure will be destroyed. Cannot function as a polarizing element
However, due to the fineness, although a grid is formed on the surface of the transparent substrate (glass), it is difficult to distinguish with the naked eye.

Embodiment Construction

[0054] figure 1 It is a schematic configuration diagram showing a light box (lamp) of the polarized light irradiation device according to the first embodiment of the present invention. This figure is a cross-sectional view in a direction perpendicular to the longitudinal direction of the light box. In addition, in this figure, the structure of a lighting device etc. of a lamp is abbreviate|omitted and shown.

[0055] The light box 1 is equipped with the light irradiation part 10, the water-cooled cooler (cooler) 20 of the upper part of the light irradiation part 10, and the blower (blower) 30. The light irradiation unit 10 has a lamp 11 and a reflector 12 that reflects light from the lamp 11 . As shown by the solid arrow in the figure, the light from the lamp 11 is irradiated to the workpiece W via the wire grid polarizing element 81 directly or after being reflected by the mirror 12 .

[0056] The blower 30 generates cooling air for cooling the lamp 11 or the reflector 12...

Abstract

The invention provides a polarized light irradiating device that comprises a wire grid polarization element, the device is constructed in such a way that during the maintenance of the device, the optic grid is not subject to damage caused by finger contact or articles falling on a grid forming surface of the wire grid polarization element of the device. The solution of the present invention is that an arrangement is made such that the grid forming surface of the wire grid polarization element faces a light source. As such, it is feasible to dispose an optic filter that protects the grid forming surface exactly above the grid forming surface (between the polarization element and the light source).

Description

[0001] The present invention is a divisional application of an application with a filing date of January 24, 2013, an application number of 201310027795.0, and an invention titled polarized light irradiation device. technical field [0002] The present invention relates to a polarized light irradiation device for aligning an alignment film of a liquid crystal cell or an alignment layer of a viewing angle compensation film by irradiating polarized light of a predetermined wavelength, and more particularly to a polarized light irradiation device using a wire grid polarizing element. Background technique [0003] In recent years, in the alignment treatment of the alignment film of the liquid crystal display element represented by the liquid crystal panel or the alignment layer of the viewing angle compensation film, etc., the method called photo-alignment is used to perform alignment by irradiating polarized light with a wavelength in the ultraviolet range. technology. Hereinaf...
