A method for manufacturing liquid crystal cells is disclosed, in which a pair of large-area glass substrates are put together, opposite to each other and spaced a small distance apart from each other, so that a plurality of liquid crystal cells are integrally formed between the glass substrates, and by splitting the glass substrate assembly, the individual cells are separated from one another. Each of the glass substrates has a plurality of regions defined on the surface thereof to serve as substrate sections for liquid crystal cell units and desired electrodes are formed on the regions. Grooves having a substantially U-shaped cross section are cut along the boundary lines bordering the respective regions on that surface of each substrate on which the desired electrodes are formed, while linear scratches are formed in the surface of the substrate opposite to the electrode-carrying surface, corresponding in position to the U-shaped grooves. The splitting operation is performed by placing the glass substrate assembly on two parallel supports and by subjecting the assembly to bending distortion with application of a pressing force. The configuration of the U-shape of the groove and the position at which the pressing force is applied is determined depending on the thickness of the glass substrate.

Method for manufacturing liquid crystal display elements

A method for producing liquid crystal cells is disclosed, in which a pair of large-area glass substrates are put together, opposite to each other and spaced a small distance apart from each other to form integrally a plurality of liquid crystal cells between the substrates, and by splitting the glass substrate assembly, the individual cells are separated from one another. Each of the glass substrates, which have the same structure, has first regions to serve as upper substrate sections and second regions to serve as lower substrate sections disposed alternately thereon and predetermined electrodes are formed on the first and the second regions. The two glass substrates are disposed face to face with each other in such a manner that the first and the second regions of one substrate are opposite to the second and the first regions of the other substrate. The splitting operation is performed by placing the glass substrate assembly on two parallel supports and by subjecting the assembly to bending distortion by applying a pressing force. The pressing force is determined depending on the relationship between the distance between the supports and the degree of the bending distortion.
