Abstract
Abstract In a connection structure for a liquid crystal display device between the terminal of a liquid crystal display device and a flexible flat cable, the end of the cover film of the flexible flat cable rides over the end of the substrate of the liquid crystal display device, and the electroconductive pattern of the flexible flat cable is in electrical connection with the terminal of said liquid crystal display device. The electroconductive pattern can be prevented from damaging or disconnection, by which the reliability upon handling or movement can be improved.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
136 words
A connection structure for connecting a liquid crystal display device having a flat terminal surface and an end of a flexible flat cable having an electroconductive layer sandwiched between upper and lower cover films said upper cover film disposed on an upper side to the end of the flexible flat cable, comprising the improvement of said lower cover film disposed on a lower side facing the flat terminal surface having a portion removed from the end of the cable to expose said electroconductive layer on said lower side, an edge of said lower cover film disposed on a lower side facing the flat so as to ride on an edge of said terminal surface by a relatively short length, and the exposed portion of said electroconductive layer being fixed in electrical connection with said terminal surface.
Claim 2
Dependent Claim
136 words
