Abstract
The present invention relates to an organic light-emitting device for lighting, and more specifically relates to an organic light-emitting device for lighting whereby it is possible to achieve excellent brightness by increasing the light-emitting area per unit area of an organic light-emitting element. For this purpose, the present invention provides an organic light-emitting device comprising: a first substrate and a second substrate disposed facing each other; a frame section which is formed between the first substrate and the second substrate, and is formed on the periphery of the first substrate and the second substrate so as to hermetically close the space between the first substrate and the second substrate; and a flexible organic light-emitting element which is disposed inside of the space, and of which at least one part has a curved surface.
