Conductive pattern having first and second capping layers and display device including the same

A display device comprising:

• a substrate;
• at least one transistor disposed on the substrate;
• and
• a light emitting element disposed on the transistor,
• wherein the transistor includes at least one conductive pattern, and
• wherein the conductive pattern includes:
• a conductive layer including aluminum;
• a first capping layer disposed on the conductive layer and including titanium;
• and
• a second capping layer disposed on the first capping layer and including titanium nitride, and
• wherein a mixed region in which the aluminum and the titanium are mixed with each other is disposed in at least portions of the conductive layer and the first capping layer.
