An in-line system for fabricating a liquid crystal display-includes a sealer coating unit for coating a sealer onto a first substrate with a plurality of liquid crystal display cell regions, a liquid crystal injection unit for dropping a liquid crystal onto the first substrate coated with the sealer, and an assembly unit for assembling the first substrate with the second substrate. A sealer hardening unit hardens the sealer interposed between the first and the second substrate to thereby assemble the first and the second substrate with each other. A substrate cutting unit cuts the first and the second substrates along cutting lines through illuminating a laser beam along the cutting lines such that the first and the second substrates are severed into the liquid crystal display cell regions.

In-line system and method for manufacturing liquid crystal display

Disclosed is a method for cutting a non-metallic substrate. A designated cutting line formed on the non-metallic substrate is cut using a thermal stress generated by rapidly heating and cooling the designated cutting line. Further, a shape and an arrangement, etc., of an energy source is optimized, thereby maximizing a cutting speed of the non-metallic substrate and also precisely cutting the non-metallic substrate.
