摘要

A light-emitting device can be folded in such a manner that a flexible light-emitting panel is supported by a plurality of housings which are provided spaced from each other and the light-emitting panel is bent so that surfaces of adjacent housings are in contact with each other. Furthermore, in the light-emitting device, in which part or the whole of the housings have magnetism, the two adjacent housings can be fixed to each other by a magnetic force when the light-emitting device is used in a folded state.

說(shuō)明書

A light-emitting panel illustrated in FIG. 15 includes a substrate 401, the transistor 240, the light-emitting element 230, the insulating layer 207, the insulating layer 209, the insulating layer 211, the insulating layer 217, a space 405, the insulating layer 261, the light-blocking layer 257, the coloring layer 259, a light-receiving element (including the p-type semiconductor layer 271, the i-type semiconductor layer 273, and the n-type semiconductor layer 275), the conductive layer 281, the conductive layer 283, the insulating layer 291, the insulating layer 293, the insulating layer 295, and a substrate 403.

The light-emitting panel includes a bonding layer (not illustrated) formed in a frame shape between the substrate 401 and the substrate 403 to surround the light-emitting element 230 and the light-receiving element. The light-emitting element 230 is sealed by the bonding layer, the substrate 401, and the substrate 403.

In the light-emitting panel of this embodiment, the substrate 403 has a light-transmitting property. Light emitted from the light-emitting element 230 is extracted to the air through the coloring layer 259, the substrate 403, and the like.

The light-emitting panel of this embodiment is capable of touch operation. Specifically, proximity or contact of an object on a surface of the substrate 403 can be sensed with the light-receiving element.
