  • Method of manufacturing large-sized thin film transistor liquid crystal display panel
    Patent number: 5472889
    Abstract: A method of manufacturing a large-sized thin film transistor liquid crystal display panel in which a plurality of unit thin film transistor liquid crystal display panels are fabricated having a predetermined size on a polyimide substrate. A predetermined number of the unit thin film transistor liquid crystal display panels are arranged in a form of a matrix. The unit thin film transistor liquid crystal display panels are bonded or tiled by using an epoxy resin on a glass substrate to achieved the large-sized thin film transistor liquid crystal display panel. The interface between the unit thin film transistor liquid crystal display panels are filled up with polyimide. Gate bus lines and drain bus lines of the unit thin film transistor liquid crystal display panels arranged in the form of the matrix are electrically connected.
