In the present invention, an organic EL device is constructed to have a structure capable of suppressing degradation of characteristics. An organic EL device (100) is provided, in which at least two sub-pixels are arranged separately from each other on a plane extending in a direction perpendicular to the stacking direction. Each sub-pixel includes a first electrode (118) and a second electrode (116) stacked therein, and an organic compound layer (117) including at least a light-emitting layer is sandwiched between the first electrode (118) and the second electrode (116), and such a light-emitting layer emits light of a different color from other light-emitting layers. The side surface of the organic compound layer is covered with a thin film, and the thin film is different from sub-pixel to sub-pixel. This structure can suppress degradation of the characteristics of the organic EL device.

This invention discloses a waterproof sound-transmitting sheet. The waterproof sound-transmitting sheet includes: a waterproof sound-transmitting layer having a waterproof function and configured to transmit sound; a first adhesive layer attached to a first surface of the waterproof sound-transmitting layer; and a second adhesive layer attached to a second surface of the waterproof sound-transmitting layer located on the opposite side of the first surface, wherein the waterproof sound-transmitting layer includes a non-porous layer without pores and a porous layer laminated on the non-porous layer and containing pores.
