Abstract: Disclosed herein is a transparent organic light-emitting display (OLED) device. A first sub-pixel includes a first transparent region and a first emissive region disposed in line with the first transparent region in a first direction, and a second sub-pixel includes a second transparent region area and a second emissive region in line with the second transparent region in the first direction. The second sub-pixel is disposed adjacent to the first sub-pixel in the second direction. The first emissive region is in line with the second transparent region in a second direction, and the second emissive region is in line with the first transparent region in the second direction. In the transparent OLED device according to an exemplary embodiment of the present disclosure, emissive regions are disposed in a zigzag pattern with respect to a gate line, so that the area of the transparent regions can be enlarged, and accordingly higher transmittance can be achieved.
