  • Publication number: 20220028961
    Abstract: A display device includes a display region and a non-display region. First lines are between the substrate and the first insulating layer in the non-display region. Second lines are on a first insulating layer in the non-display region and are alternately disposed with the first lines. A second insulating layer is over the second lines and has a surface unevenness formed by the first and second lines. Third lines are over the second insulating layer and intersect the first lines and the second lines. First insulating patterns are on the second insulating layer and serve to planarize the surface unevenness. The first insulating patterns are between at least adjacent third lines in a plan view.
