摘要： A display device includes a base layer, a pixel disposed on the base layer and including a thin film transistor, and a signal line connected to the pixel. The signal line includes a metal layer and a capping layer disposed on the metal layer, including molybdenum and tantalum. The metal layer has a first light reflectance, and the capping layer has a second light reflectance that is lower than the first light reflectance of the metal layer. The capping layer includes a tip protruding from a sidewall of the metal layer, and the tip protrudes more than a contact point at which the sidewall of the metal layer contacts with the base layer when viewed in a plane. The display device has an improved external light reflection characteristic and an enhanced display quality.
