摘要： Disclosed is an organic electroluminescent device (organic EL device) which is improved in luminous efficiency, fully secure of driving stability, and of a simple configuration. The organic EL device comprises organic layers comprising a hole-transporting layer and a light-emitting layer sandwiched between an anode and a cathode. 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.

摘要： A self-emission panel and a method of manufacturing a self-emission panel which can prevent emission failures from occurring due to various factors, thereby achieving a self-emission panel that is free from emission failures. The self-emission panel is manufactured by forming a first conductive layer on a substrate directly or via other layers, forming a deposition layer including a luminescent layer on the first conductive layer, and forming a second conductive layer on the deposition layer. This manufacturing method includes: a first step of forming a sectioning layer for sectioning an opening for making a emission area on the first conductive layer after the formation of the first conductive layer; a second step of applying surface treatment to at least the surface of the first conductive layer inside the opening; and a third step of depositing a deposition layer on the first conductive layer given surface treatment in the second step.
