<p>Disclosed is a polymer light-emitting device having a light-emitting layer arranged between an anode and a cathode, and a hole transport layer arranged between the light-emitting layer and the anode. This polymer light-emitting device is characterized in that the hole transport layer is a layer containing a polymer compound which contains a repeating unit represented by the general formula (I) below, a repeating unit represented by the general formula (II) below and a repeating unit represented by the general formula (III) below.
(In the formula (I), R 1 , R 2 , R 3 and R 4 may be the same or different and respectively represent a hydrogen atom or the like; R 5 , R 6 , R 7 and R 8 may be the same or different and respectively represent an alkyl group or the like; and a, b, c and d may be the same or different and respectively represent an integer of 0-3. When a plurality of R 5 's, R 6 's, R 7 's and R 8 's are present, they may be the same as or different from one another.)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-Ar 1 -€ƒ€ƒ€ƒ€ƒ€ƒ(II)
(In the formula (II), Ar 1 represents a divalent aromatic amine.)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-Ar 2 -€ƒ€ƒ€ƒ€ƒ€ƒ(III)
(In the formula (III), Ar 2 represents an arylene group or a divalent heterocyclic group.)</p> |
