SELF-LUMINOUS DISPLAY PANEL MANUFACTURING METHOD AND SELF-LUMINOUS DISPLAY PANEL
First Claim
1. A method of manufacturing a self-luminous display panel, the method comprising:
- preparing a substrate;
forming, above the substrate, banks that are each elongated and each extend in a column direction, the banks being arranged in a row direction with spaces therebetween;
detecting a bank having a defect portion among the banks;
determining, with respect to the detected bank having the defect portion, only one of two adjacent spaces as a repair target space, the two adjacent spaces each being located between the detected bank and a bank adjacent to the detected bank in the row direction;
forming, in the repair target space, a dam structure within a predetermined distance from the defect portion, the dam structure at least partially surrounding the defect portion or being composed of a pair of dam elements disposed with the defect portion therebetween in the column direction; and
forming light-emitting layers by applying inks to the spaces between the banks, the inks containing self-luminous materials.

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.

5. A self-luminous display panel comprising:
-
a substrate; banks disposed above the substrate, the banks each being elongated and extending in a column direction and being arranged in a row direction with spaces therebetween; and light-emitting layers containing self-luminous materials, the light-emitting layers being formed by applying inks to the spaces between the banks, wherein at least one of the banks has a defect portion, and with respect to the bank having the defect portion, a dam structure is provided in only one of two adjacent spaces that are each located between the bank and a bank adjacent to the bank in the row direction, the dam structure being within a predetermined distance from the defect portion, and at least partially surrounding the defect portion or being composed of a pair of dam elements disposed with the defect portion therebetween in the column direction. - View Dependent Claims (6, 7, 8)
