摘要： A light irradiation device for an exposure apparatus allowing implementation of photo-alignment process with a simple configuration is provided. The light irradiation device is configured using a light source with a plurality of LEDs, and a polarizing element that receives light from the light source and applies the light transmitted through the polarizing element to a workpiece. An optical axis of each of the LEDs is set in such a manner as to have a first angle θ1 to the workpiece. A second angle θ2 as an angle half of a light distribution angle of the light emitted from each of the LEDs is set smaller than the first angle θ1.
