ORGANIC EL DISPLAY PANEL AND DISPLAY DEVICE

摘要

Disclosed is an organic EL display panel comprising: an organic EL substrate containing a plurality of organic light emitting elements respectively arranged in a plurality of light emitting regions that are separated by partitions; and a black matrix arranged opposite to the organic EL substrate. In the black matrix, there are formed a plurality of apertures that permit passage of light from the aforementioned plurality of organic light emitting elements. The plurality of organic light emitting elements include: a first organic light emitting element that includes an organic light emitting layer that emits light with a first light emission colour; and a second organic light emitting element containing an organic light emitting layer that emits light of a second light emission colour different from the aforementioned first colour. The plurality of apertures include a first aperture corresponding to the first organic light emitting element; and a second aperture corresponding to the second organic light emitting element. The light emission efficiency of the first organic light emitting element is lower than the light emission efficiency of the second organic light emitting element and the thermal conductivity at the periphery of the first aperture is higher than the thermal conductivity at the periphery of the second aperture.
