Abstract

An LCD module uses a flexible printed circuit (FPC) instead of a gate or a source drive printed circuit board (PCB) so that size of area by which a tape carrier package (TCP) is thermocompression molded can be substantially decreased and thus reducing a difference in the degree of thermal expansion between PCB and TCP. As a result, a slim and lightweight LCD module can be obtained, and a misalignment or a warpage of TCP can be prevented.
