Liquid crystal display device and method of making the same

A method of making a liquid crystal display device, comprising the steps of:

• assembling a first electrode substrate having terminals at its edge portion, a second electrode substrate opposite to said first electrode substrate, and a liquid crystal material held between said first and second electrode substrates into a liquid crystal display device;
• preparing a flexible printed circuit board including a base film and a signal line layer put along said base film, and an anisotropic conductive film made of a thermosetting isolation resin and electrically conductive particles dispersed in said isolation resin, said anisotropic conductive film having a connecting portion and an extra portion extending from said connecting portion;
• aligning said signal line layer of said flexible printed circuit board with said connecting portion of said anisotropic conductive film and said terminals of said first electrode substrate;
• thermally pressure-contacting said signal layer of said flexible printed circuit board to said terminals of said first electrode substrate through said connecting portion of said anisotropic conductive film;
• forming a support member out of said connecting portion of said flexible printed circuit board at said edge portion of said first electrode substrate during said thermally pressure-contacting step;
• and
• making a protection layer out of said extraportion of said anisotropic film during said thermally pressure-contacting step.
