ORGANIC ELECTROLUMINESCENCE DEVICE

摘要

An organic EL device includes at least one insulating bank disposed on a translucent substrate, a translucent electrode in contact with the bank, an organic layer containing a light-emitting layer and formed on the translucent electrode, and a reflection electrode formed on the organic layer. The bank is made from a translucent dielectric material having a low refractive index that is equal to or less than that of the organic layer. The bank has a side face that is a slope inclined with respect to the translucent substrate. The side face has a concave surface shape that faces the light-emitting layer from a slope in contact with the light-emitting layer to a slope in contact with a portion of the organic layer in the vicinity of the reflection electrode.
