Patent number: 8780568Abstract: A flexible display device comprises a device substrate and a flexible circuit substrate, and achieves high reliability of electrical connection. The device substrate includes a flexible substrate, a display unit and a first terminal part. The flexible circuit substrate includes a second terminal part. An ACF including conductive particles connects the first and second terminal parts. Each conductive particle consists of a core part covered by a metal layer. An electrode layer and a cushioning layer are provided between the flexible substrate and the first terminal part. A quotient of a sum of a product of average particle diameter and elastic modulus for the core part, and a product of double average thickness and elastic modulus for the metal layer, divided by a sum of products of average thickness and elastic modulus for the first terminal part, the cushioning layer and the electrode layer, is no greater than 1.5.Type: GrantFiled: December 14, 2012Date of Patent: July 15, 2014Assignee: Panasonic CorporationInventors: Takashi Osako, Yuji Tanaka

Patent number: 8779296Abstract: A wiring board is provided which can prevent a metal electrode from corroding due to a defect in a transparent conductive electrode covering an end face of an organic insulating film. An active-matrix substrate includes: a glass substrate; a metal wire provided on the glass substrate; a gate insulating film covering the metal wire; an interlayer insulating film covering the gate insulating film; and a transparent electrode formed on the interlayer insulating film. The scanning wire provided with a terminal area where the transparent electrode is laminated directly on the scanning wire. The transparent electrode extends over the terminal area in such a way as to cover an end face of the interlayer insulating film that faces the terminal area and an end face of the gate insulating film that faces the terminal area.Type: GrantFiled: May 18, 2010Date of Patent: July 15, 2014Assignee: Sharp Kabushiki KaishaInventors: Hiromitsu Katsui, Kenichi Kitoh, Wataru Nakamura

Patent number: 8742260Abstract: Provided is a circuit board device in which printed wiring boards 11, 12 are connected to each other electrically using a anisotropic conductive member 15 disposed between the printed wiring boards 11, 12. The anisotropic conductive member 15 comprises: an insulating elastic resin material 16; fine metal wires 17 having a middle portion embedded within the insulating elastic resin material 16 so as to connect corresponding connecting terminals of the printed wiring boards 11, 12; and resin layers 18 exhibiting a flexural rigidity greater than that of the insulating elastic resin material. An assembly composed of the printed wiring boards 11, 12 and anisotropic conductive member 15 is curved. The resin layers are shape-retaining resins for maintaining the curvature of respective ones of principal surfaces of the anisotropic conductive member 15 made to conform to curvature of the printed wiring boards 11, 12.Type: GrantFiled: October 5, 2007Date of Patent: June 3, 2014Assignee: NEC CorporationInventor: Junya Sato
