Abstract: An input sensing unit includes a first metal pattern layer including a plurality of first conductive lines extending in a first direction. A first insulating layer is disposed on the first metal pattern layer. A second metal pattern layer is positioned above the first insulating layer and includes a plurality of second conductive lines extending in a second direction intersecting the first direction. A second insulating layer is disposed on the second metal pattern layer. A sensing electrode is disposed on the second insulating layer and is electrically connected to the second metal pattern layer through a contact hole defined in the second insulating layer. An anti-reflection pattern layer is disposed on the first and second metal pattern layers to overlap the first and second metal pattern layers along a direction orthogonal to an upper surface of the anti-reflection pattern layer.
