Abstract: A display panel includes a first conductive layer including a first layer, a second layer, and a third layer sequentially stacked, and a second conductive layer on the first conductive layer and contacting the third layer. The first layer includes a first metal. The second layer includes the first metal and oxygen in a first composition ratio. The third layer includes the first metal and oxygen at a second composition ratio. The second composition ratio is smaller than the first composition ratio. Conductivity of the third layer is higher than conductivity of the second layer. The first composition ratio is a ratio of an atom percent of the first metal to an atom percent of oxygen in the second layer. The second composition ratio is a ratio of an atom percent of the first metal to an atom percent of oxygen in the third layer.
