The display device includes: a flexible display panel including a display portion in which scanning lines and signal lines cross each other; a supporting portion for supporting an end portion of the flexible display panel; a signal line driver circuit for outputting a signal to the signal line, which is provided for the supporting portion; and a scanning line driver circuit for outputting a signal to the scanning line, which is provided for a flexible surface of the display panel in a direction which is perpendicular or substantially perpendicular to the supporting portion.

Display device

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.

Electronic book

An object of the present invention is to reduce the thickness of a lighting device using an electroluminescent material. Another object of the present invention is to simplify the structure of a lighting device using an electroluminescent material to reduce cost. A light-emitting element having a stacked structure of a first electrode layer, an EL layer, and a second electrode layer is provided over a substrate having an opening in its center, and a first connecting portion and a second connecting portion for supplying electric power to the light-emitting element are provided in the center of the substrate (in the vicinity of the opening provided in the substrate).
