A light-emitting device includes a surface-light-emitting unit, a substrate, a holding sheet, and a sealing sheet. The surface-light-emitting unit has a light-emitting surface and a non-light-emitting surface, and emits light from the light-emitting surface. The substrate has a mounting surface and a non-mounting surface provided to be flush with the light-emitting surface, and has a power source mounted on the mounting surface. The holding sheet is provided to face the non-mounting surface and the light-emitting surface provided to be flush with the non-mounting surface. The sealing sheet is disposed on the side opposite to the holding sheet with respect to the surface-light-emitting unit and the substrate, and provided to cover the surface-light-emitting unit and the power source. The light-emitting device is disposed so that the holding sheet comes to the installation surface side. With such a structure, the light-emitting device that can be stably disposed on the installation surface is provided.

The present disclosure relates to a display device and a mobile terminal including the same. The display device can include a display panel including a first pixel array region, a light transmissive region, and a second pixel array region and a light guide module disposed below the light transmissive region.
