Abstract
Provided are a mask, a method of manufacturing a mask, a light radiating device, a method of radiating light and a method of manufacturing an ordered photo-alignment layer. By the mask, collimated light or nearly collimated light may be irradiated with uniform illumination on the object to be irradiated. Further, by the mask, light may be effectively irradiated even in a state where the object to be irradiated has the curved surface.
Claims18
A mask, comprising:
- a transparent thin film, of which a thickness is from 10 μm to 300 μm;
- a metal layer which is on one surface of the transparent thin film and has at least one opening configured to guide light to an object to be irradiated;
- and
- a structure formed of a transparent material and having a curved surface on which the transparent thin film is attached so as to be in a curved shape.
