Claim:
1. A display device, comprising: two light-emitting elements with different turn-on voltages, wherein the two light-emitting elements respectively include a patterned electrode, a common layer, a patterned light-emitting layer, and a common electrode, and wherein the light-emitting element with a lower turn-on voltage among the two light-emitting elements includes a functional layer configured to suppress holes from being leaked from the light-emitting layer with a higher turn-on voltage through the common layer and from moving into the patterned light-emitting layer of the light-emitting element with the lower turn-on voltage, when the light-emitting element with the higher turn-on voltage among the two light-emitting elements is driven at a low gray scale.
