摘要： An organic electroluminescent device has 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.

摘要： An organic electroluminescence display includes a first electrode and an auxiliary wire each either on or in a substrate. A luminescent layer is over the first electrode, and a hole transport layer is between the luminescent layer and the first electrode. The hole transport layer extends from over the first electrode to over the auxiliary wire. A second electrode is over the luminescent layer and extends from over the first electrode to over the auxiliary wire. A metal layer is over the auxiliary wire between the hole transport layer and the second electrode. The second electrode and the auxiliary wire are electrically connected via the hole transport layer and the metal layer. The metal layer comprises a metal, wherein a difference of a work function value of the metal minus an absolute value of an energy level of a lowest unoccupied molecular orbit of the hole transport layer is at most approximately 0.5 eV.
