  • Patent number: 7314403
    Abstract: An apparatus and method for fabricating a liquid crystal display panel are disclosed. In case of the single mode that liquid crystal display panels are fabricated with the same size on a large glass substrate, unit liquid crystal display panels are kept and discarded not to proceed with a follow-up process. Thus, a material waste is restrained and a yield can be improved. Meanwhile, in case of the multi-mode that liquid crystal display panels are fabricated with difference sizes on a large glass substrate, sub-models are kept, and then after completing the process for the main models, a follow-up process if performed on the sub-models. Thus, use efficiency of the glass substrate can be maximized to improve a productivity and a unit cost of the product can be reduced.
