ABSTRACT:
A method of manufacturing a liquid crystal display device, in which predetermined portions of two glass plates bonded to each other with a sealing member interposed therebetween and constituting the display device, can be cut without turning over the bonded two glass plates and without breaking necessary portions thereof. In the method of manufacturing the liquid crystal display device, first, an upper one of the bonded two glass plates is half cut from its upper surface with a blade, and unnecessary portions of the upper glass plate are removed by the use of a vacuum suction head. Thereafter, predetermined portions of exposed portions of a lower one of the bonded two glass plates are fully cut with the blade. In accordance with it, it is not necessary to turn over the the bonded two glass plates-to cut it into a plurality of units, and, therefore, a cutting process can be performed automatically. Further, since portions of the bonded two glass plates other than the unnecessary portions thereof are prevented from breakage, the yield of products can be increased.
