Abstract
The present invention relates to an organic EL display panel having an organic light emitting layer having a uniform film thickness. The organic EL display panel of the present invention includes: a substrate; linear banks placed on the substrate and defining a linear region on the substrate; and at least two organic EL elements aligned in a row each linear region, and, each of the organic EL elements includes: an anode placed on the substrate; a hole injection layer formed with an metallic oxide and placed on the anode; an organic light emitting layer placed on the hole injection layer; and a cathode placed on the organic light emitting layer. The hole injection layer is concavely curved or convexly curved, the hole injection layer is partly placed under the banks; and the organic light emitting layer is formed by applying an organic light emitting material in the linear region.
