An object of the present invention is to provide an image display device that is free from disconnection in a connection structure between given substrates even when operated in a hot and humid environment. An image display device according to a preferred embodiment of the invention has a TFT substrate and an FPC. The TFT substrate has a plurality of first terminals capable of application of potential. The FPC has second terminals that are connected respectively with the first terminals through an anisotropic conductive film and that are thicker than the first terminals. The second terminals include a high-potential terminal, a low-potential terminal, and a dummy terminal. The high-potential terminal is supplied with a relatively high potential that contributes to the display operation. The low-potential terminal is supplied with a relatively low potential that contributes to the display operation. The dummy terminal is positioned between the high-potential terminal and the low-potential terminal and is supplied with a potential not contributing to the display operation.
