LIGHT EMITTING ELEMENT, LIGHT EMITTING DEVICE, AND ELECTRONIC DEVICE |
摘要 |
It is an object of the present invention to provide a functional layer for protecting a light emitting element from being deteriorated by a physical or chemical influence when the light emitting element is manufactured or driven, and to attain extension of lifetime of an element and improvement of element characteristics without increasing a drive voltage and degrading transmittance and color purity by providing such a functional layer. One feature of the present invention is to provide a buffer layer made of a composite material for a light emitting element including aromatic hydrocarbon containing at least one vinyl skeleton and metal oxide in part of a light emitting substance containing layer, in the light emitting element fowled by interposing the light emitting substance containing layer between a pair of electrodes. The composite material for a light emitting element for forming the buffer layer of the present invention has high conductivity and is superior in transparency.
