In a surface light-emitting unit, a wiring board (60) includes, on its side on which a holding substrate (11) is located, an external-wire connecting portion (40). An opening (11h) is provided in the holding substrate (11). The wiring board (60) is disposed to cover the opening (11h) and allow the external-wire connecting portion (40) to be exposed, through the opening (11h), toward a surface of the holding substrate (11) opposite to the surface thereof on which the wiring board (60) is held. With an external wire connected to the external-wire connecting portion (40), a surface of the wiring board (60) located in the opening (11h) is sealed by a second sealing member.

The present U.S. patent application is a U.S. National Phase Application under 35 USC 371 of International Application PCT/JP2014/071711 filed on Aug. 20, 2014. This application claims priority under the Paris Convention of Japanese patent application No. 2013-182971 filed on Sep. 4, 2013, the entirety of which is incorporated herein by reference.
The present invention relates to a structure of a surface light-emitting unit in which a surface light-emitting device is used.
Recently, a surface light-emitting unit has been proposed in which a planer light-emitting device using organic EL (electroluminescence) or the like is used. Japanese Laid-Open Patent Publication No. 2000-133438 (PTD 1) discloses an illuminating body that can be mounted on a curved portion and a method for manufacturing the illuminating body.
FIG. 1 is a plan view showing a basic configuration of a surface light-emitting panel including a surface light-emitting device in an embodiment.
FIG. 2 is a cross-sectional view along II-II in FIG. 1 as seen in the direction of the arrows.
FIG. 3 is a plan view showing a schematic configuration of a surface light-emitting unit in an embodiment as seen from a light-emitting side of the surface light-emitting unit.
In the following, a description will be given, with reference to the drawings, of a surface light-emitting device in each embodiment based on the present invention, a surface light-emitting panel in which this surface light-emitting device is used, and a surface light-emitting unit in which this surface light-emitting panel is used. In the case where the number, amount, or the like is mentioned in connection with embodiments described below, the scope of the present invention is not necessarily limited to the number, amount, or the like unless otherwise specified. The same parts or corresponding parts are denoted by the same reference numerals, and a description thereof will not be repeated in some cases. It is originally intended that characteristics of the embodiments are used in combination as appropriate.
Surface Light-Emitting Device 1 and Surface Light-Emitting Panel 10
Referring to FIGS. 1 and 2, a basic configuration of a surface light-emitting panel 10 in the present embodiment will be described. FIG. 1 is a plan view showing surface light-emitting panel 10, illustrating surface light-emitting panel 10 as seen from a back surface 19 of surface light-emitting panel 10. FIG. 2 is a cross-sectional view along II-II in FIG. 1 as seen in the direction of the arrows.
