A first electrode conduction path surrounds at least one half of a periphery of the light-emitting region and connects the first electrode pad and the second electrode pad. A circuit board is fixed near the first vertex. A first electrode wire is configured to adhere to the first electrode pad and the second electrode pad. A second electrode wire is configured to adhere directly or indirectly to the second electrode pad region in the second electrode stretched region.

In order to achieve the increased efficiency of an organic light-emitting element, there is a need to reduce the influence of non-radiative recombination of electronhole pairs except for surface plasmon polariton excitation, to convert most of exciton energy into visible light, and to tremendously improve the luminous efficiency of the organic light-emitting element. An organic light-emitting element according to the present invention includes a reflective electrode, a transparent electrode, and a light-emitting layer placed between the reflective electrode and the transparent electrode, and the organic light-emitting element is configured so that the light-emitting layer contains a host and a first dopant, and for the first dopant, one of the vertical component and horizontal component of the average value for transition dipole moments with respect to a substrate surface is larger than the other of the components.

摘要:
Disclosed herein are a light-emitting device of tip emission type which maintains a stable emission efficiency without leakage current and a process for production of the light-emitting device. The light-emitting device (10) consists of a substrate (1), a lower electrode (4), an organic layer (6) which includes at least an emission layer (6c), and a transparent upper electrode (7) provided on the organic layer (6) which are sequentially formed on top of the other. The lower electrode (4) has a double-layer structure composed of a metallic layer (2a) and a buffering thin film (3c) formed thereon. The buffering thin film (3a) is formed from an oxide of the metallic material constituting the metallic layer (2a), the oxide having a higher conductivity than the organic layer (6), or formed from an oxide of chromium. The thus formed buffering thin film (3a) reduces the surface roughness of the metallic layer (2a) in the lower electrode (4) of double-layer structure. The reduced surface roughness provides a uniform space between the lower electrode (4) and the transparent upper electrode (7).
