- FIG. 14 is a perspective view showing the configuration of the light emitting device 10 according to Modification 7. As shown in FIG. The light emitting device 10 according to this modification has the same configuration as that of Modification 6 except for the following points.
- the groove 250 is not provided in the second base material 200, and instead, the adhesive layer 254 is provided on the surface of the second base material 200 opposite to 100.
- the adhesive layer 254 is provided for attaching the light emitting device 10 to a wall or the like.
- the adhesive layer 254 is covered with a protective sheet 256.
- the protective sheet 256 is accommodated in the slit 260 after being peeled off from the adhesive layer 254. And after peeling the light-emitting device 10 from a wall etc., the adhesion layer 254 is again covered with the protective sheet 256.
- FIG. Such a method of use is employed, for example, when the light emitting device 10 is attached to or peeled off from a wall or the like.
