A display panel including a substrate; first, second, and third lower electrodes; first and second column banks; first, second, and third organic light-emitting layers; and an upper electrode. When a first ink for forming the first organic light-emitting layer, a second ink for forming the second organic light-emitting layer, and a third ink for forming the third organic light-emitting layer are applied, ink-separating capability of the first column bank for separating the first ink and the second ink is lower than ink-separating capability of the second column bank for separating the second ink and the third ink, and ink-separating capability depends on: (i) a height of the first and second column banks, or (ii) liquid repellency of the first column bank against the first ink and the second ink and liquid repellency of the second column bank against the second ink and the third ink.
