    Abstract: A display panel having a low-resistance conductive layers is disclosed. An example display panel includes a first conductive layer having a first layer, a second layer, a third layer, a fourth layer, and a fifth layer that are sequentially stacked with the first layer being electrically conductive with the fifth layer, and a second conductive layer that is disposed on the first conductive layer and that in contact with the fifth layer. The first layer and the third layer include a first metal. Further, the second layer includes a second metal that is different from the first metal. Still further, the fourth layer includes the first metal and oxygen in a first composition ratio, and the fifth layer includes the first metal and oxygen in a second composition ratio with the first composition ratio and the second composition ratio being different from each other.
