Abstract
To improve an image quality of an organic EL display by utilizing characteristics of a dual emission type organic light emitting element. A display device includes a first substrate over which a plurality of organic light emitting elements are provided and a second substrate over which an organic light emitting element is provided. The first and second substrates are facing each other. At least either the organic light emitting elements provided over the first substrate or the organic light emitting element provided over the second substrate emit/emits light toward both surfaces of the first or second substrate. Light emitting regions of the organic light emitting elements provided over the first substrate are overlapped with a light emitting region of the organic light emitting element provided over the second substrate as seen from the second substrate.
