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.
