Abstract: 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.

Abstract: A display device and a method of manufacturing a display device are provided. A method of manufacturing a display device may include: forming a sacrificial layer on a carrier glass; forming a first substrate layer on the sacrificial layer, the first substrate layer including an organic insulation material; forming a first through-hole in the first substrate layer, the first through-hole passing through the first substrate layer; forming a wiring on an upper surface of the first substrate layer, the wiring extending into the first through-hole; sequentially forming a circuit layer, an emission layer, and an encapsulation layer on the wiring; separating the sacrificial layer and the carrier glass from the first substrate layer by irradiating the sacrificial layer with a laser; and attaching a driving element on a lower surface of the first substrate layer, the driving element being electrically connected to the wiring through the first through-hole.
