Patent number: 7160634Abstract: An organic electroluminescent device having an organic layer between a pair of electrodes. The organic layer (in particular, a hole-transporting layer) has a polymer of a vinyl compound represented by the following formula (1): wherein R1 and R2 are the same or different, each representing a hydrogen atom, a halogen atom, an alkyl group or an alkoxy group. The glass transition temperature of the polymer is about 200 to 250° C., and the polymer has high heat-resistance. Thus, the use of the polymer improves heat resistance of an organic EL device.Type: GrantFiled: October 14, 2005Date of Patent: January 9, 2007Assignees: Daicel Chemical Industries, Ltd.Inventors: Yasuhiko Shirota, Yutaka Ohsedo, Kazuyuki Moriwaki, Kenji Okumoto
