Patent ID: 8786819

Claim:
A method for manufacturing a plastic flat display, comprising: a first process of preparing an upper indium tin oxide (ITO) film substrate by bonding a transparent ITO film substrate on a base film, and preparing a lower flexible printed circuit board (FPCB) electrode substrate; a second process of patterning the upper ITO film substrate after the first process; a third process of printing an alignment layer on the upper ITO film substrate; a fourth process of printing an alignment layer on the lower FPCB electrode substrate; a fifth process of printing a thermosetting sealant on the upper ITO film substrate and distributing spacers on the lower FPCB electrode substrate after the fourth process; a sixth process of aligning and coupling the upper ITO film substrate and the lower FPCB electrode substrate with each other through thermal pressing after the fifth process; and a seventh process of injecting liquid crystals under a vacuum condition into a space between the upper ITO film substrate and the lower FPCB electrode substrate after the sixth process, wherein the lower FPCB electrode substrate is an integrated type substrate for supplying an electrical signal to the plastic flat display, wherein the lower FPCB electrode substrate includes a base film, a copper electrode laminated on the base film, and a gold plating layer laminated on the copper electrode, and a protection film laminated on a part of a region of the gold plating layer, wherein the fourth process is performed by coating the alignment layer on the gold plating layer uncovered by the protection film in the lower FPCB electrode substrate, and wherein the sixth process is performed by aligning the alignment layer of the upper ITO film substrate and the alignment layer on the gold-plating layer of the lower FPCB.
