Organic electro-luminescence display device

A top-emission organic electro-luminescence display device in which an element substrate having a display region in which pixels each having an organic electro-luminescence layer sandwiched between an upper electrode and a lower electrode are formed in a matrix form is sealed by a sealing substrate and an image is formed on a side of the sealing substrate, wherein

• the organic electro-luminescence layer comprises an electron transporting layer, a light emitting layer, and a hole transporting layer, wherein the electron transporting layer is formed through co-evaporation of an organic material and cesium, and
• a desiccant which comprises a material identical to the material of the electron transporting layer and comprises a co-evaporation layer having a greater composition ratio of cesium than the electron transporting layer is placed without overlapping the light emitting layer.
