Abstract
A liquid crystal display device in which a liquid crystal layer is sandwiched between a TFT substrate having pixel electrodes and opposed electrodes formed and an opposed substrate, an external conductive film of a transparent electrode is formed on an outer surface of the opposed substrate, and an upper polarizing plate is arranged on the external conductive film. A portion of the external conductive film that is not covered with the upper polarizing plate is electrically connected to a ground potential through a conductive thermocompression bonding tape. The conductive thermocompression bonding tape is configured so that w3<w2<w1 is satisfied, wherein w1 represents a width of the conductive thermocompression bonding tape, w2 represents the width of the conductive thermocompression bonding tape electrically connected to the external conductive film, and w3 represents the width of the conductive thermocompression bonding tape electrically connected to a predetermined portion where the ground potential is provided.
