Abstract: A sputtering target includes a first target part and a second target part both including a metal oxide and adjacent to each other and a target dividing part disposed between a first target part and a second target part. The target dividing part includes a same metal element as a metal element included in a first target part and a second target part. Therefore, size and/or length of the sputtering target may be increased. Thus, efficiency of a manufacturing process of the sputtering target is improved and a manufacturing cost is reduced. In addition, even after a thin film is deposited on a target substrate using the sputtering target, stains caused by sputtering of non-uniform amounts of metal elements by location on the target substrate do not occur on a target substrate. In addition, the uniformity of a thin film deposited on a target substrate is secured by using the sputtering target. Thus, process quality of a sputtering process is improved.

Abstract: A display panel includes a substrate including a component area, a display area at least partially surrounding the component area, and a first non-display area at least partially surrounding the display area. A first wiring is in the display area and extends in a first direction to face the component area. A second wiring is in the display area and extends in the first direction to face the component area. The second wiring is spaced apart from the first wiring with the component area therebetween. A pixel circuit is connected to one of the first and second wirings and includes at least one thin-film transistor. A display element is connected to the pixel circuit. A cross-sectional area of the first wiring crossing in a second direction that is perpendicular to the first direction is different from a cross-sectional area of the second wiring crossing in the second direction.

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.
