Abstract: An exposure device may include an exposure head that may radiate an exposure beam onto a substrate on a stage, a support that may be provided on the stage to support the exposure head, a chamber that may accommodate the stage, the exposure head, and the support. The exposure device may include first protrusions that may be disposed on an outer circumference of the support adjacent to an inner wall of the chamber, and second protrusions that may be disposed on the inner wall of the chamber surrounding the outer circumference of the support. The first and second protrusions may overlap each other in a plan view.
