1. A display device comprising:
a substrate; and
a display element part on the substrate, and comprising:
a light emitting element configured to emit light in a display direction; and
a bank pattern that protrudes in the display direction,
wherein the bank pattern comprises:
a first layer of the bank pattern comprising a first same semiconductor material as a first layer of the light emitting element; and
a second layer of the bank pattern comprising a second same semiconductor material as a second layer of the light emitting element, the second same semiconductor material being different from the first same semiconductor material.
