Abrégé
(EN) A liquid crystal display panel provided with a conductive film (12) that covers the upper surface of a CF glass substrate (11) or the upper surface of a polarizing plate (13) stacked on the CF glass substrate. The conductive film and a ground electrode (16) upon a TFT glass substrate (10) are electrically connected by a conductive tape (20) having adhesive properties. A conductive paste (22, 23) is adhered on the top thereof, at a location such that the conductive paste spans both the conductive tape and the conductive film, and at a location such that the conductive paste spans both the conductive tape and the ground electrode. The conductive tape has extra length such that the total length of the conductive tape is longer than the shortest distance between the connection location for the conductive tape and the conductive film and the connection location for the conductive tape and the ground electrode.
(FR) La présente invention concerne un panneau d'affichage à cristaux liquides qui comprend un film conducteur (12) recouvrant la surface supérieure d'un substrat en verre CF (11) ou la surface supérieure d'une plaque de polarisation (13) empilée sur ledit substrat en verre CF. Le film conducteur et une électrode de masse (16) sur un substrat en verre TFT (10) sont connectés électriquement grâce à une bande conductrice (20) qui possède des propriétés adhésives. Une pâte conductrice (22, 23) adhère sur le dessus de ladite bande, à un emplacement qui la fait s'étendre sur la bande conductrice et sur le film conducteur, et à un emplacement qui la fait s'étendre sur la bande conductrice et sur l'électrode de masse. Ladite bande conductrice présente une longueur supplémentaire, de manière à ce que la longueur totale de la bande conductrice soit plus grande que la distance la plus courte entre l'emplacement de connexion pour la bande conductrice et le film conducteur et l'emplacement de connexion pour la bande conductrice et l'électrode de masse.
(JA) 　ＣＦガラス基板（１１）の上面、またはＣＦガラス基板に重ねられた偏光板（１３）の上面を覆う導電膜（１２）が設けられる。導電膜とＴＦＴガラス基板（１０）上のグラウンド電極（１６）が粘着性を有する導電テープ（２０）により電気的に接続される。その上で、導電テープと導電膜の両方にまたがる形で、また導電テープとグラウンド電極の両方にまたがる形で、それぞれの箇所に導電ペースト（２２）（２３）が付着せしめられる。導電テープには、導電テープと導電膜との接続箇所と導電テープとグラウンド電極との接続箇所の間の最短距離よりも全長が長くなるように、長さのゆとりが与えられる。
