Abstract

In an organic EL display panel, one sealing substrate is shared between two organic EL substrates, thereby achieving thinning and lightening of the panel body. The display panel includes a sealing substrate having a first concave portion and a second concave portion opposite the first concave portion, a first transparent glass substrate hermetically sealed on the first concave portion, a first organic light emitting element formed on a surface of the first transparent glass substrate, a first desiccant disposed on a bottom surface of the first concave portion, a second transparent glass substrate hermetically sealed on a the second concave portion, a second organic light emitting element formed on a surface of the second transparent glass substrate, a second desiccant disposed on a surface of the second concave portion, wherein the first organic light emitting element and the second organic light emitting element achieve a shared use of the sealing substrate.
