摘要： A high-molecular compound including a group indicated by general formula (11) as a repeating unit. In formula (11) n1 indicates an integer of 1-3. Ar1 indicates an arylene group, a divalent aromatic heterocyclic group, or a divalent aromatic amine residue, and these groups may have a substituent group. If there is a plurality of Ar1, the Ar1 can be the same or can be different. R11 indicates a hydrogen atom, an alkyl group, an aryl group, a monovalent aromatic heterocyclic group, or an aralkyl group, and said groups may have a substituent group. The plurality of R11 can be the same or can be different. However, at least three of the R11 are an alkyl group, an aryl group, a monovalent aromatic heterocyclic group, or an aralkyl group.

摘要： A method for driving a light emitting device is provided. The light emitting device includes an anode, a cathode, a light emitting layer disposed between the anode and the cathode, and a hole transporting layer disposed between the anode and the light emitting layer. The hole transporting layer includes a cross-linked body of a crosslinkable material. According to the method, the light emitting device is driven by pulse voltage in which a first voltage not lower than the light emission start voltage of the light emitting device and a second voltage lower than the light emission start voltage of the light emitting device are alternately switched. A light emitting apparatus equipped with the light emitting device and a driving apparatus which drives the light emitting device by pulse voltage is also provided.
