Abstract: An organic EL display panel in which pixels are arranged in a matrix, including: light-emitting layers disposed above pixel electrode layers in intervals between adjacent ones of column banks; an opposing electrode layer disposed above the light-emitting layers, the opposing electrode layer including a light-transmissive material; column light-shielding layers disposed higher than the pixel electrode layers, extending in the column direction, arranged side-by-side in the row direction, and overlapping row-direction edge portions of the pixel electrode layers in plan view of a substrate; and row light-shielding layers disposed higher than the pixel electrode layers, extending in the row direction, arranged side-by-side in the column direction, overlapping column-direction edge portions of the pixel electrode layers and partially overlapping contact regions in plan view of the substrate.

Abstract: Provided is an organic EL display panel manufacturing method. The organic EL display panel includes a plurality of semiconductor elements. The method includes: forming, on a planarization film formed above the semiconductor elements, lower electrodes in one-to-one correspondence with the pixels; forming an organic layer including a light-emitting layer on the lower electrodes; forming an upper electrode on the organic layer; detecting any of the lower electrodes that includes a defect; and forming, on the planarization film or any of the lower electrodes that includes a defect, a protrusion for connecting the lower electrode and the upper electrode.

Abstract: According to one embodiment, a display device capable of preventing spreading of color mixture even in a case where a bank has a defect, and preventing light emission failure in a pixel is provided. A plurality of first banks are provided on a substrate. A plurality of second banks are arranged to cross the first banks, and separate a plurality of pixels with the first banks. A plurality of repair members having liquid repellency are provided on the first banks located on both sides of a pixel corresponding to a defective portion of the second bank, of the pixels.

Abstract: A display panel 1 includes a substrate 12, a first column bank 30A, a second column bank 30B, a third column bank 30C, first row banks 40A in a first column region 35A, second row banks 40B in a second column region 35B, blue organic light-emitting elements 11B, and green organic light-emitting elements 11G. The number of high row banks between blue organic light-emitting elements is less than the number of high row banks between green organic light-emitting elements.
