Abstract: A liquid crystal display device with spacers integrally formed at a plastic substrate. The liquid crystal display device comprises: upper and lower substrates joined with liquid crystals interposed there-between, at least one substrate of which is made of plastic; a driving electrode for the liquid crystals formed at the lower substrate; polarizers attached at respective rear surfaces of the upper and lower substrates; and spacers interposed between the upper and lower substrates to maintain cell gaps, wherein the spacers are integrally formed at the substrate, and concurrently act as posts. Also, spacers can be integrally formed at either one of the lower plastic substrate and the upper plastic substrate, or the spacers can be integrally formed at both the lower plastic substrate and the upper plastic substrate, and the spacers have a height of “cell gap±a”, wherein the cell gap is 0.2 to 10 &mgr;m and “a” is not more than 1 &mgr;m.
