摘要： An organic EL display apparatus which can improve the reliability thereof, by avoiding a leak current which occurs after an operating time, without reducing the product yield. The organic EL display apparatus is comprised of an organic EL panel section, and a driving section which has a reverse voltage restriction unit (means for restricting a reverse voltage) for restricting a reverse voltage which is applied when organic EL devices are not lighted. When a breakdown voltage with respect to a preset thickness do of the organic material layer has been Vb, the reverse voltage restriction unit will not only set the reverse voltage Vm (to be applied during a non-lighting period) to Vm

The light-emitting layer contains a fluorescent light-emitting material and an electron- and/or exciton-blocking layer containing an indolocarbazole derivative represented by general formula (2) is disposed between the hole-transporting layer and the light-emitting layer so as to be adjacent to the light-emitting layer. In general formula (2), ring B is a heterocyclic ring fused to the adjacent rings and represented by formula (1c), Z is an n-valent aromatic hydrocarbon group or aromatic heterocyclic group, and n is 1 or 2.
