  • Patent number: 7943931
    Abstract: A substrate includes an array area and a data pad area adjacent to the array area. A gate line, a data line and a switching device are formed in the array area of the substrate. A data pad extending from an end of the data line and a supporter provided between the substrate and the data pad are provided in a data pad area to allow the data pad to be placed at a higher position than a passivation layer. Thus, a contact resistance occurring between an anisotropic conductive film and a bump and a contact resistance occurring between the anisotropic conductive film and the data pad are reduced.
