    摘要: 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.

    摘要: A display device includes a first electrode and a second electrode that are spaced apart from and facing each other; a light-blocking layer disposed above the first electrode and the second electrode; and at least one light-emitting element disposed between the first electrode and the second electrode. The light-blocking layer includes a light-blocking portion absorbing light and an opening pattern. The light-blocking portion includes an area partially overlapping the first electrode and the second electrode. The at least one opening pattern exposes portions of the first and second electrodes facing each other and at least a portion of an area between the first and second electrodes facing each other. The at least one light-emitting element overlaps the at least one opening pattern.
