  • Patent number: 8461054
    Abstract: A method of manufacturing a liquid crystal display device which includes pixel electrodes and common electrodes which are alternatively arranged in each pixel defined on a substrate, including the steps of: forming a conductive film on the substrate; forming a mask layer, of which etching selection ratio is different from the conductive layer, on the conductive layer; forming a photo-resist pattern of a fixed pattern on the mask layer; forming a mask pattern, which has an undercut shape to the photo-resist pattern, by etching the mask layer by use of the photo-resist pattern as an etching mask; removing the photo-resist pattern; and etching the conductive film by use of the mask pattern as an etching mask, to provide at least any one of the common electrode and the pixel electrode.

  • Patent number: 8228455
    Abstract: The present invention relates a method for forming a pattern includes the steps of forming a thin film on a substrate, coating a photoresist film on the thin film, aligning a mask over the photoresist film, the mask formed on a base material, including a light shielding portion having a linear supporting portion and an uneven portion at a boundary of the supporting portion, and a transmission portion defined at regions excluding the light shielding portion, exposing the photoresist film with the mask thereon to a UV beam of a wavelength greater than 300nm to cause refraction in the vicinity of the uneven portion, and developing the photoresist film exposed thus to form a photoresist film pattern, and patterning the thin film by using the photoresist film pattern thus formed.

  • Patent number: 7977171
    Abstract: A method of fabricating a thin film transistor substrate for reducing a mask process and, at the same time removing a transparent electrode ITO which remains at a non-display area by a contact hole filling process is disclosed. In the method of fabricating the thin film transistor substrate having a display area and a non-display area, a gate pattern is formed at the exterior of the display area. A gate insulating film is formed on a substrate provided with a gate pattern, and then a data pattern is formed. And a protective film is formed on an entire substrate provided with a data pattern, and then a conductive pattern, and then a conductive pattern, which is comprised of a pixel electrode which is formed at a display area, and a lower gate pad electrode and a lower data pad electrode which are formed at a non-display area, is formed.
