This charge transport material, which comprises a compound represented by the formula, has a high efficiency after storage at a high temperature, and has a high highest attained brightness (R101 and R102 each independently represents an alkyl group, an aryl group, a heteroaryl group, a fluorine atom, or a silyl group, and furthermore may be substituted by these groups or an amino group; a condensed ring aryl structure or a condensed ring heteroaryl structure are not contained in R101 or R102; there is a total of at least five single-ring aromatic rings (the aromatic rings being six-membered rings of which the members are configured from carbon atoms or nitrogen atoms) in R101 and R102; n101 is an integer from 0 to 11; n102 is an integer from 0-9; the plurality of R101 and R102 may be the same or different; and AA1-AA9 each independently represent CH (the hydrogen atom of CH being optionally substituted with R102) or a nitrogen atom). |
