A display device comprising:
- a substrate;
- a bank on the substrate and defining an opening;
- a first electrode on the opening and the bank;
- a second electrode on the opening and the bank;
- and
- a light emitting element located in the opening and electrically connected to the first electrode and the second electrode,

5 more elements
A method for fabricating a display device, comprising:
- forming a photoresist layer on a substrate;
- exposing the photoresist layer using a halftone mask comprising a light blocking portion to block light, a first light transmitting portion to transmit light as it is, and a second light transmitting portion to transmit a part of the light;
- developing the photoresist layer to concurrently form an opening, a partition wall having a first height, and a bank having a second height;
- forming a first electrode and a second electrode on the opening, the partition wall, and the bank, the first electrode and the second electrode being spaced from each other;
- and
- applying a coating solution containing light emitting elements in the opening, forming an electric field between the first electrode and the second electrode to align the light emitting elements, and removing the coating solution.
