Patent number: 9985228Abstract: A flexible display is bent in an intermediate region such that a first region and a second region overlap each other. A spacer is disposed inside a bend of the flexible display. The spacer includes a front-side region overlapping the first region, a back-side region overlapping the second region, and a guide region overlapping the intermediate region and regulating the bend. The spacer includes, in the front-side region, a first step and a first bottom surface recessed below the guide region. The spacer includes, in the back-side region, a second step and a second bottom surface recessed below the guide region. An interval between a second reinforcing film and a second raised surface located at the second step is larger than an interval between a first reinforcing film and a first raised surface located at the first step.Type: GrantFiled: February 1, 2017Date of Patent: May 29, 2018Assignee: Japan Display Inc.Inventors: Kazuto Tsuruoka, Naohisa Andou, Takashi Saeki, Megumi Senda, Yusuke Goto
