Abstract: To provide a highly reliable light-emitting device and especially a light-emitting device which can be formed without use of a metal mask and includes a plurality of light-emitting elements. A structural body at least an end of which has an acute-angled shape is provided so that the end can pass downward through an electrically conductive film formed over the insulating layer and can be at least in contact with an insulating layer having elasticity, thereby physically separating the electrically conductive film, and the electrically conductive films are thus electrically insulated from each other. Such a structure may be provided between adjacent light-emitting elements so that the light-emitting elements can be electrically insulated from each other in the light-emitting device.

Abstract: An electronic device has a structure in which two portions between which a bent portion of a display panel is positioned are each fixed to a housing. The electronic device takes two forms of a form in which the display panel is opened and a form in which the display panel is folded in three. The electronic device includes a mechanism for sliding two housings parallel to each other. The display panel is changed in shape so that a portion where a display surface of the display panel is convexly curved and a portion where the display surface of the display panel is concavely curved in the folded state move in directions parallel and opposite to each other. At this time, the two portions of the display panel which are supported by the housings are slid while their display surfaces maintain a state parallel to each other.
