Abstract:
A liquid crystal display device, comprising:a liquid crystal panel including first and second electrode substrates provided opposite to each other and a liquid crystal material held between said electrode substrates;terminals disposed at an edge portion of said first electrode substrate;a flexible printed circuit board including a base film and a signal line layer put along said base film;an electrically anisotropic conductive film made of a thermosetting isolation resin and electrically conductive particles dispersed therein;said anisotropic film including a connecting portion to connect said signal line layer of said flexible printed circuit board to said terminals at the edge portion of said panel and an extra portion extending from said connecting portion;a support member formed out of said connecting portion of said anisotropic conductive film at said edge portion of said first substrate when said flexible printed circuit, said connecting portion of said anisotropic conductive film, and said terminals of said first electrode substrate are processed to be thermally pressure-contacted to each other; anda protection layer formed by said extra portion of said anisotropic film to protect said signal line layer of said flexible printed circuit board during said thermally pressure contacting process.
