<P>PROBLEM TO BE SOLVED: To provide an aromatic amine compound having excellent heat resistance, and to provide a light-emitting element, a light-emitting device, and an electronic apparatus having excellent heat resistance. <P>SOLUTION: There is provided the aromatic amine compound which is represented by the general formula (7). There are also provided the light-emitting element, the light-emitting device and the electronic apparatus using the compound. The light-emitting element is constituted of: a first electrode 102, a layer 103 containing a substance of excellent hole-injection property, a layer 104 containing a substance of excellent hole-transport property, a layer 105 containing a substance of light-emission property, and a layer 106 composed of a substance of excellent electron transport property, which are laminated in the order on the first electrode; and a second electrode 107. In the formula, Ar<SP POS="POST">1</SP>to Ar<SP POS="POST">3</SP>each represents one of a 6-12C aryl group and a 4-9C heteroaromatic ring group respectively, Y<SP POS="POST">1</SP>to Y<SP POS="POST">3</SP>represent a 6-25C arylene group (therein, the structural formula (17-3) is excluded), R<SP POS="POST">11</SP>to R<SP POS="POST">16</SP>each represents one of hydrogen atom, a 1-4C alkyl group and a 6-25C aryl group, and R<SP POS="POST">21</SP>to R<SP POS="POST">23</SP>each represents one of hydrogen atom, methyl group and methoxy group. <P>COPYRIGHT: (C)2013,JPO&INPIT |
