Title:
LIGHT-EMITTING DEVICE
Document Type and Number:
Japanese Patent JP2016046423
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance luminous efficiency while suppressing deterioration of a luminous layer.SOLUTION: The organic EL element of a light-emitting device is constituted by laminating a first electrode, an organic layer and a second electrode, in this order, on a substrate. The organic layer has a luminous layer 240. The luminous layer 240 has a part 242. Preferably, the part 242 of the luminous layer 240 is located at the center of the luminous layer 240 in the thickness direction, or closer to the second electrode. The part 242 is formed of an organic material (second organic material) different from the material (first organic material) composing the luminous layer 240.SELECTED DRAWING: Figure 3
