Abstract:
(EN) A liquid crystal display panel with an ultra-narrow lower bezel and a corresponding manufacturing method. The liquid crystal display panel comprises a TFT array substrate (2), a CF substrate (1), and a liquid crystal layer located therebetween. The TFT array substrate (2) comprises a substrate, and the substrate comprises an active display area (20) in the middle and peripheral area (21) located outside of the active display area (20). At least a part of a lower bezel area (22) of the peripheral area (21) extends out of the CF substrate (1). A pattern (24) is etched on the lower bezel area (22), and an insulating layer (3) is provided on the pattern. The upper side of the insulating layer (3) is etched to form a plurality of LCD conductive pads (250), a plurality of via holes (30) is formed on the insulating layer (3), and each LCD conductive pad (250) on the upper side of the insulating layer (3) is electrically connected to the pattern (24) etched on the lower bezel area (22) of the substrate of the TFT array substrate (2) by means of one via hole (30), so that the ultra-narrow lower bezel of the liquid crystal display panel is achieved.
(FR) L'invention concerne un panneau d'affichage à cristaux liquides doté d'une lunette inférieure ultra-étroite et un procédé de fabrication correspondant. Le panneau d'affichage à cristaux liquides comprend un substrat de réseau TFT (2), un substrat CF (1), et une couche de cristaux liquides située entre ceux-ci. Le substrat de réseau TFT (2) comprend un substrat, et le substrat comprend une zone d'affichage active (20) dans la zone centrale et périphérique (21) située à l'extérieur de la zone d'affichage active (20). Au moins une partie d'une zone de lunette inférieure (22) de la zone périphérique (21) s'étend hors du substrat CF (1). Un motif (24) est gravé sur la zone de lunette inférieure (22), et une couche isolante (3) est disposée sur le motif. Le côté supérieur de la couche isolante (3) est gravé pour former une pluralité de pastilles conductrices LCD (250), une pluralité de trous d'interconnexion (30) est formée sur la couche isolante (3), et chaque pastille conductrice LCD (250) sur le côté supérieur de la couche isolante (3) est électriquement connectée au motif (24) gravé sur la zone de lunette inférieure (22) du substrat du substrat de réseau TFT (2) au moyen d'un trou de raccordement (30), de telle sorte que la lunette inférieure ultra-étroite du panneau d'affichage à cristaux liquides soit obtenue.
(ZH) 一种具有超窄下边框的液晶显示面板及相应的制造方法,液晶显示面板包括TFT阵列基板(2),CF基板(1),以及位于两者之间的液晶层,TFT阵列基板(2)包括有基板,基板包括位于中间的有效显示区域(20)及位于有效显示区域(20)外侧的外围区域(21),外围区域(21)的下边框区域(22)至少一部分伸出CF基板(1)之外,在下边框区域(22)上蚀刻有图案(24),其上设置有绝缘层(3),在绝缘层(3)上侧蚀刻形成多个LCD导电焊盘(250),绝缘层(3)上形成有多个过孔(30),绝缘层(3)上侧的每一个LCD导电焊盘(250)通过一个过孔(30)与TFT阵列基板(2)的基板下边框区域(22)上蚀刻的图案(24)进行电气连接,可以实现液晶显示面板下边框的超窄化。
