LIGHT ILLUMINATING APPARATUS FOR PHOTO-ALIGNMENT

摘要

The present invention improves alignment properties by including a polarizing unit which is divided into unit polarizers and detecting the polarization direction of each unit polarizer. A photoalignment illuminating apparatus according to the present invention includes the polarizing unit which includes a plurality of unit polarizers which are adjacently arranged, a scan unit which scans a UV ray from a polarized light emitting unit in a preset scan direction with regard to a substrate loaded on a stage by moving the stage or the polarized light emitting unit, and a polarized direction detecting unit which detects the polarization direction of the UV ray emitted from the polarized light emitting unit at each unit polarizer. [Reference numerals] (AA) Emitting area; (BB) Scan direction
