  • Electronic Book
    Publication number: 20210149449
    Abstract: An e-book reader in which destruction of a driver circuit at the time when a flexible panel is handled is inhibited. In addition, an e-book reader having a simplified structure. A plurality of flexible display panels each including a display portion in which display control is performed by a scan line driver circuit and a signal line driver circuit, and a binding portion fastening the plurality of display panels together are included. The signal line driver circuit is provided inside the binding portion, and the scan line driver circuit is provided at the edge of the display panel in a direction perpendicular to the binding portion.
