ORGANIC ELECTROLUMINESCENT ELEMENT AND LUMINESCENT APPARATUS EMPLOYING THE SAME

摘要

An organic electroluminescent element which contains a compound having a high fluorescence yield and excellent thermal stability and emits a stable red light having a high color purity and a high luminance. The organic electroluminescent element comprises a glass substrate (1) and, disposed thereon in this order, a transparent ITO electrode (2), a hole-transporting layer (6), an electron-transporting layer (7), and a metal electrode (3), wherein the hole-transporting layer (6) and/or the electron-transporting layer (7) comprises a layer of a mixture comprising at least one aminostyryl compound represented by the following general formula [I] and a hole-blocking layer (30) is disposed between the hole-transporting layer (6) and the electron-transporting layer (7). General formula [I] Y<1>-CH=CH-X<1>-CH=CH-Y<2> In the general formula [I], X<1> is aryl, e.g., phenyl having a substituent such as nitro; and Y<1> and Y<2> each is a group having aminophenyl, etc. in the skeleton.
