Apparatus and method for fabricating liquid crystal display panel

#This application claims the benefit of Korean Patent Application No. 2002-15970, filed on Mar. 25, 2002, which is hereby incorporated by reference for all purposes as if fully set forth herein.

#1. Field of the Invention

#The present invention relates to an apparatus and method for fabricating a liquid crystal display panel, and more particularly, to an apparatus and method for fabricating a liquid crystal display panel in which a defective unit liquid crystal display panel is discarded so that follow-up processes are not performed on the defective unit liquid crystal display panel when a single mode that liquid crystal display panels are fabricated with the same size on a large glass substrate, and in case of a multi-mode that liquid crystal display panels are fabricated with different sizes, sub-models are kept to proceed with a follow-up process.

#The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.

#In the drawings:

#FIG. 1 is an exemplary view illustrating a sectional of a plurality of unit liquid crystal display panels formed by attaching a first mother substrate with thin film transistor array substrates formed thereon and a second mother substrates with color filter substrates formed thereon;

#Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

#FIG. 8 is a block diagram of an apparatus for fabricating of a liquid crystal display panel in accordance with an embodiment of the present invention.

#As shown in FIG. 8, an apparatus for fabricating a liquid crystal display panel includes an attaching unit 301 for attaching a first mother substrate with thin film transistor array substrates formed thereon and a second mother substrate with color filter substrates formed thereon; a cutting unit 302 for cutting the first and second mother substrates into unit liquid crystal display panels; a cut section checking unit 303 for checking the cut section of the cut unit liquid crystal display panel; a buffering cassette 304 for sorting out and holding a defective unit liquid crystal display panel (in case of a single mode in which the unit liquid crystal display panels are the same in size), and sorting out and holding sub-model unit liquid crystal display panels (in case of a multi-mode in which the unit liquid crystal display panels are different in size); a controller 305 for providing information on the single mode and the multi-mode to the buffering cassette 304; a grinding unit 306 for grinding a marginal portion of a perfect non-defective unit liquid crystal display panel in case of the single mode and grinding a marginal portion of the unit liquid crystal display panel of a main model in case of the multi-mode; and a final checking unit 307 for checking the grinding unit liquid crystal display panels.
