1. A display device comprising:
a circuit substrate;
light-emitting elements disposed on the circuit substrate and electrically connected to the circuit substrate, respectively;
a color conversion layer disposed on a first light-emitting element of the light-emitting elements; and
a bank comprising multiple strip structures extending along a first direction and arranged along a second direction intersecting the first direction, wherein a first strip structure of the multiple strip structures is disposed between the first light-emitting element and a second light-emitting element of the light-emitting elements, and there is a gap between the first strip structure and the color conversion layer,
wherein no color conversion layer is disposed on the second light-emitting element, and a gap between the first strip structure and a second strip structure of the multiple strip structures disposed respectively on two opposite sides of the second light-emitting element is less than a gap between the first strip structure and a third strip structure of the multiple strip structures disposed respectively on two opposite sides of the first light-emitting element.
