An organic EL display panel having a functional layer with a uniform film thickness is provided. The organic EL display panel of the present invention contains anode electrodes set on the substrate; organic EL layers set on the anode electrodes; line-state banks defining the organic EL layers in a line-state region; second banks defining two or more regions in the line-state region. The line-state banks and the second banks contain a fluorine resin, a fluorine concentration of the fluorine resin gradually changes along a thickness direction of each of the line-state bank and the second bank, and the fluorine concentration at a top of each of the line-state bank and the second bank is higher than the fluorine concentration at a bottom surface of each of the line-state bank and the second bank.
