Among end portions of a plurality of organic compound layers patterned by photolithography, an end portion in an area that is not located between luminescent elements and that is located in an area covered with a second electrode is formed to have a smaller inclination angle than that of an end portion located between the luminescent elements.

Organic luminescent device and method for manufacturing the same

A method of manufacturing an organic electroluminescence device includes forming a first organic electroluminescence layer at least on a first lower electrode, forming a first protective layer on the first organic electroluminescence layer, processing the first organic electroluminescence layer and the first protective layer, forming a second organic electroluminescence layer at least on a second lower electrode, forming a second protective layer on the second organic electroluminescence layer, and processing the second organic electroluminescence layer and the second protective layer. The second organic electroluminescence layer and the second protective layer, which have been processed by the processing the second organic electroluminescence layer and the second protective layer, cover an end portion of the first organic electroluminescence layer and an end portion of the first protective layer, which have been processed by the processing the first organic electroluminescence layer and the first protective layer.

Method of manufacturing organic electroluminescence device

Provided is an organic light-emitting device having little apparent deterioration of a durable luminance. The organic light-emitting device includes a hole transport layer and a light-emitting layer which are located in a predetermined order between a reflection electrode for reflecting light and an electrode for transmitting light, the hole transport layer being in contact with the reflection electrode and made of an organic compound, and the light-emitting layer being made of an organic compound, wherein an optical film thickness L of the hole transport layer is set in a range of 0.25&#x3bb;&#xd7;(2n &#x2212;1.7) to 0.25&#x3bb;&#xd7;(2n&#x2212;1.3), where &#x3bb; indicates an emission wavelength and n indicates a positive integer.

Multi-color display apparatus

To provide a light-emitting device which can emit light with high luminance and high efficiency, and is excellent in durability. The light-emitting device includes an organic compound layer containing a phenanthroline compound represented by the general formula [I] and a carbonate.
