    摘要: An organic EL device includes: an anode (3), a cathode (4) and an organic thin-film layer (10) interposed between the anode (3) and the cathode (4), in which the organic thin-film layer (10) includes: an emitting layer (5) containing a host material and a phosphorescent material; and a hole transporting layer (6) provided adjacent to the anode (3) relative to the emitting layer (5). The hole transporting layer (6) includes a first hole transporting layer (61) and a second hole transporting layer (62) that are sequentially layered on the anode, in which the first hole transporting layer (61) contains an amino compound substituted by an aromatic substituent represented by a formula (1) below and the second hole transporting layer (62) contains at least one of compounds represented by formulae (2) to (5) below.
