  • Patent number: 9645434
    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.

  • Patent number: 7777838
    Abstract: A liquid crystal display (LCD) comprises: a first substrate and a second substrate; a liquid crystal layer between the first and the second substrates; and a fluorescent color filter responding to light over the first substrate, thereby the fluorescent color filter supplies the light to the liquid crystal layer. A method for fabricating a LCD includes: preparing first and second substrates; depositing fluorescent material over the first substrate to form a color filter, the fluorescent material emitting the visible light in responding to the ULTRAVIOLET rays; and forming a liquid crystal layer between the first and second substrates.
