Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/141249
Kind Code:
A1
Abstract:
An organic electroluminescent element using a compound represented by general formula (AA) has high luminous efficiency and excellent color purity, while being suppressed in chromaticity change due to driving deterioration. (In the formula, X represents CRaRb (wherein each of Ra and Rb represents a hydrogen atom or a substituent), NRc (wherein Rc represents a hydrogen atom or a substituent), O, S or SiRdRe (wherein each of Rd and Re represents a hydrogen atom or a substituent); each of A1-A4 represents CRf (wherein Rf represents a hydrogen atom or a substituent) or N; and each of R1-R8 represents a hydrogen atom or a substituent.)
