Liquid crystal display device with relationship of a width of conductive thermocompression bonding tape to a width of a bonding thereof to an external conductive film and to an earth pad

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 having color filters formed, 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,

• wherein an earth pad connected to the ground is formed on the TFT substrate,
• a portion of the external conductive film that is not covered with the upper polarizing plate is connected to the earth pad through a conductive thermocompression bonding tape, and
• w3<w2<w1 is satisfied, if a direction parallel with a side of the opposed substrate on which the conductive thermocompression bonding tape is arranged is defined as a width, where w1 represents the width of the conductive thermocompression bonding tape, w2 represents the width of the conductive thermocompressed bonded portion of the conductive thermocompression bonding tape bonding to the external conductive film, and w3 represents the width of the conductive thermocompressed bonded portion of the conductive thermocompression bonding tape bonding to the earth pad.
