Abstract:
1. An organic EL display panel, comprising: a substrate; an interlayer insulating layer that is provided on the substrate; first electrodes that are provided on the interlayer insulating layer so as to correspond one-to-one to element formation regions arranged in rows and columns above the substrate; banks that are provided extending in columns to partition the element formation regions arranged in rows; organic light-emitting layers that are provided above the first electrodes in one-to-one correspondence, and each contain an organic light-emitting material having a light-emitting color differing between each two adjacent element formation regions arranged in rows; and second electrodes that are provided above the organic light-emitting layers in one-to-one correspondence, and are opposite in polarity to the first electrodes, wherein the interlayer insulating layer has a first opening that corresponds in position to an interval between each two adjacent first electrodes in rows, the banks each have a buried part and a main part that are integrally formed, the buried part fills the interval and the first opening, and the main part is a protrusion of the buried part, the main part has, on a top surface directly opposite the buried part, a first recess having a corresponding shape to the first opening.
