Abstract: A display device includes a plurality of pixels and an upper signal line providing a data signal to the pixels. The upper signal line includes a first upper signal line including a first metal material, a second upper signal line including a second metal material which is different from the first metal material, and a third upper signal line including the first metal material. The first, second and third upper signal lines are arranged in order and respectively electrically connected to a plurality of connection lines including the second metal material. The connection lines are connected to a plurality of lower signal lines.
