Organic electroluminescent display device
View Patent ↗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 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.
1. An organic EL display device comprising:
a first transparent substrate;
a first light emitting element disposed over an inner surface of said first transparent substrate;
a second transparent substrate;
a second light emitting element formed over an inner surface of said second transparent substrate;
a sealing substrate having a first portion on one surface and a second portion on an opposite surface relative to said first portion, said sealing substrate further including at least one opening that allows communication between said first and second portions; and
wherein said inner surface of said first transparent substrate and said first portion of said sealing substrate are facing each other, and said inner surface of said second transparent substrate and said second portion of said sealing substrate are facing each other.
2. An organic EL display device according to claim 1 ,
wherein a first absorbent layer is disposed over an inner surface of said first transparent substrate in an area other than the area of said first light emitting element.
3. An organic EL display device according to claim 1 ,
wherein said second light emitting element includes a larger light emitting area than a light emitting area of said first light emitting element.
4. An organic display device according to claim 1 ,
wherein a first absorbent layer is disposed over an inner surface of said first transparent substrate in an area other than the area of said first light emitting element; and
wherein said second light emitting element includes a larger light emitting area than a light emitting area of said first light emitting element.
5. An organic EL display device according to claim 1 ,
wherein light emits from said first light emitting element through the first transparent substrate.
6. An organic EL display device according to claim 5 ,
wherein light emits from said second light emitting element through the second transparent substrate.
