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
