Abstract:
1. A pressure-welded structure of flexible circuit boards in a liquid crystal display device having lead terminals of flexible circuit boards each having a terminal surface connected with a plurality of terminals aligned on an end surface of a TFT glass substrate via anisotropic conductive films, wherein a stiffening layer of resin having a substantially uniform thickness is applied on a surface opposite to the terminal surface of each flexible circuit board, and an end portion of the resin is 0.1 to 10 mm away from an end portion of a resin applied on the terminal surface of each flexible circuit board, whereby the respective resins applied on the terminal surface and on the other surface overlap each other by 0.1 to 10 mm and wherein the resin applied on the surface opposite to the terminal surface is about 40 percent thicker than the resin applied to the terminal surface.
