Disclosed is a method for fabricating a lightweight and thin liquid crystal display (LCD) device, using a supplementary substrate for processing of a thin glass substrate. Inactive gas is sprayed onto the surface of the substrate to thus remove OH groups from the surface, before the thin glass substrate and the supplementary substrate are attached to each other. Under such configuration, the supplementary substrate can be easily separated from a completed liquid crystal panel which is in an attached cell state, without any damages.

Method of fabricating lightweight and thin liquid crystal display device

In a method of fabricating a lightweight and thin liquid crystal display (LCD), when an auxiliary substrate is used to perform a process of a thin glass substrate, the auxiliary substrate is separated from the thin glass substrate by detaching an edge portion between the thin glass substrate and the auxiliary substrate using a knife and then injecting air into the edge portion using an air knife, so that the auxiliary substrate can be easily separated from a liquid crystal panel in a cell state, which is attached by completing the process. Further, it is possible to optimize the shape of a push pin for forming a point at which the detachment of the edge portion is started.
