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.

Abstract: A display device includes a first pixel region (FPR), a second pixel region (SPR), a color conversion pattern (CCP), a first overcoat layer (FOL), a barrier layer (BL), a second overcoat layer (SOL), a liquid crystal layer (LCL), and a switching element (SE). The FPR is configured to display a first color (FC). The SPR is adjacent the FPR, and is configured to display a second color (SC) of a shorter peak wavelength than the FC. The CCP is disposed in the FPR, and is configured to: convert a color of incident light into the FC; and output converted light of the FC. The FOL is disposed on the CCP. The BL is of an inorganic material, and is disposed on the FOL. The SOL is of an organic material, and is disposed on the BL. The LCL is disposed on the SOL. The SE is disposed on the LCL.
