More Information
Summary:A red light emitting organic electroluminescence device (11) has a structure in which an organic layer (14) including a light emitting layer (14c) is sandwiched between an anode (13) and a cathode (15). In the organic electroluminescence device (11), the light emitting layer (14c) contains, as a host material, a polycyclic aromatic hydrocarbon compound of which a parent skeleton is 4 to 7 rings, together with a red light emitting guest material. In addition, a photosensitizing layer (14d) containing a phosphorescent material having an organic material is provided adjacently to the light emitting layer (14c). Consequently, there are provided a red light organic electroluminescence device being sufficiently good in luminous efficiency and color purity and a display apparatus using the same.
