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.
