Abstract:
1. An organic light emitting device, comprising: an anode; a cathode; and a luminescent substance placed between said anode and said cathode, comprising: a first molecular substance in which an absorption edge of the longest wavelength in an optical absorption spectrum is less than 400 nm, said first molecular substance having a structure represented by a general formula (2) shown below where R1 to R10 are identical to or different from one another each representing a hydrogen atom or a substituent; R1 and R6 may be bonded to each other to form a ring; adjacent ones of R1 to R5 and adjacent ones of R6 to R10 may be bonded to each other to form rings; and A1 and A2 are identical to or different from each other each representing a hydrogen atom or a substituent; and a second molecular substance emitting the light of the spectral component in the wavelength range of red, which is 2-(1,1-Dimethylethyl)-6-(2-(2,3,6,7-tetrahydro-1,1,7,7-tetramethyl-1H, 5H-benzo(ij)quinolizin-9-yl)ethenyl)-4H-pyran-4H-y-lidene)propanedinitrile represented by a formula (10) shown below wherein said luminescent substance further includes a substance emitting light through a triplet excited state, and wherein the organic light emitting device makes blue or white emission.
