Abstract: Discussed are a transparent display device and a manufacturing method thereof, which may reduce diffraction grating. The transparent display device includes gate lines and data lines formed on a substrate and crossing each other with a gate insulator film interposed therebetween to define pixel areas, common lines formed on the substrate and being parallel to the gate lines, thin film transistors formed in the respective pixel areas, pixel electrodes connected to the thin film transistors, and common electrodes connected to the common lines and alternating with the pixel electrodes. In the transparent display device, blocks between the pixel electrodes and the common electrodes are reduced or increased in width by an equal difference with increasing distance from both edges of each pixel area proximate to the data lines or by an equal difference with decreasing distance to the center of the pixel area.
