Abstract

PURPOSE: To perform cutting and separating readily with good dimensional accuracy by beforehand providing the bonded layers of low-melting point glass in the cutting and separating positions to individual cells and putting scribe lines only to one of the glasses in the process for multiple-piece production of liquid crystal display cells.
CONSTITUTION: At the time of assembling multiple-piece production upper and lower substrates, low-melting point glass 16 is beforehand printed and fired in the final intended cutting positions 16 to bury the gap 17 for liquid crystal material, thence liquid crystals are injected and injection ports 18 are sealed by soldering, after which acribe lines 20 are put only to one substrate 18 with a one-point diamond cutter 21, thence tensile stress is given in the direction orthogonal to the lines, whereby the substrates are cut and separated along the breaking lines 15.
