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.

Claims (36)

1. A display device, comprising:

a substrate;

a plurality of first banks provided on the substrate;

a plurality of second banks being arranged to cross the first banks, and separating a plurality of pixels with the first banks; and

a plurality of repair members having liquid repellency, being provided on the first banks located on both sides of a pixel corresponding to a defective portion of the second bank.

2. The device according to claim 1 ,

wherein the first banks have a first height, and the second banks have a second height greater than the first height, and have a linear shape along the pixels.

3. The device according to claim 1 ,

wherein at least one of the repair members is semi spherical.

4. The device according to claim 3 ,

wherein the repair members are provided at intervals.

5. The device according to claim 1 ,

wherein the repair members are provided in dots.

6. The device according to claim 5 ,
