Title
(EN) DISPLAY PANEL AND MANUFACTURING METHOD THEREOF

Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a display panel in which device performance is improved.

SOLUTION: A display panel 1 includes a substrate 11, first, second and third lower electrodes 12a, 12b, 12c, first and second column banks 131, 132, first, second and third organic light-emitting layers 15B, 15B, 15G, and an upper electrode 18. When first, second and third inks for forming the first, second and third organic light-emitting layers 15B, 15B, 15G are applied, ink separability for separating these inks is lower in the first column bank 131 than in the second column bank 132, and ink separability is based on the height of the first and second column banks 131, 132, or liquid repellency for the first, second and third inks of first and second column banks 131, 132.
