International ClassH01L 21/00AbstractA method for fabricating LCDs based on a plastic film is disclosed. The disclosed method comprise the steps of: attaching a double-sided adhesive tape to a supporting plate using one side thereof; fixing a plastic film substrate onto the supporting plate using an unused side of the double-sided adhesive tape after putting the plastic film substrate and the supporting plate with the double-sided adhesive tape attached thereto through a predetermined thermal treatment to thereby form a lower substrate including the supporting plate, plastic film substrate and the double-sided adhesive tape therebetween; preparing an upper substrate using the steps described above; conducting a substrate forming process on each of the lower and the upper substrates; depositing an orientation film on both the lower substrate and the upper substrate, and rubbing the orientation film; detaching the plastic film substrate from the supporting plate of the lower and the upper substrates to form a plastic front substrate and a plastic rear substrate; spraying spacer particles on one of the plastic front substrate and the plastic rear substrate, and dispensing a sealant on the other substrate; and joining the plastic front substrate and the plastic rear substrate at a distance, injecting a liquid crystal material through an injection opening, and closing the injection opening to thereby form a plastic film liquid crystal display.Other References
