AI summary
A transparent organic light emitting display device may include a transparent base substrate, a semiconductor device disposed on the transparent base substrate, a display structure electrically connected to the semiconductor device, and a protection layer including a blue dye disposed on the display structure. The protection layer may improve the transparency of the transparent base substrate by calibrating discoloration of the transparent base substrate. Thus, the transparent display device including the protection layer may ensure an enhanced transparency. Further, the transparent display device may have an enhanced mechanical strength and an increased heat resistance because of the transparent base substrate.
