Self-luminous display panel manufacturing method and self-luminous display panel

Abstract

A method of manufacturing a self-luminous display panel, includes: preparing a substrate; forming banks above the substrate; detecting a bank having a defect portion; determining, with respect to the detected bank, only one of two adjacent spaces as a repair target space; forming a dam structure in the repair target space; and forming light-emitting layers. The banks are elongated and extend in a column direction, and are arranged in a row direction with spaces therebetween. The two adjacent spaces are each located between the detected bank and an adjacent bank. The dam structure is located within a predetermined distance from the defect portion, and at least partially surrounds the defect portion or is composed of a pair of dam elements disposed with the defect portion therebetween in the column direction. The light-emitting layers are formed by applying inks to the spaces between the banks. The inks contain self-luminous materials.
