  • Publication number: 20240147798
    Abstract: A display apparatus includes a substrate and pad terminals arranged on the substrate in a first direction in a pad area and including a first pad terminal disposed at outer side and an ith pad terminal disposed at inner side. Each of the pad terminals includes a lower conductive layer, convex portions, and an upper conductive layer. An overlapping area between the lower conductive layer of the first pad terminal and the convex portions is different from an overlapping area between the lower conductive layer of the ith pad terminal and the convex portions in a plan view.

  • Publication number: 20240122011
    Abstract: A display device includes a first conductive pattern layer connected to a signal line, a second conductive pattern layer connected to the first conductive pattern layer, and an insulation pattern layer disposed between the signal line and the second conductive pattern layer and overlapping the second conductive pattern layer. The second conductive pattern layer exposes a portion of an upper surface and a side surface of the insulation pattern layer. The second conductive pattern layer includes first and second edge portions disposed on the upper surface of the insulation pattern layer and facing each other in a second direction intersecting a first direction. A distance between the first and second edge portions decreases as moving along the first direction in a first region of the upper surface of the insulation pattern layer, and increases as moving along the first direction in a second region of the upper surface.

  • Patent number: 11871630
    Abstract: A display device includes a base layer, a pixel disposed on the base layer, a signal line electrically connected to the pixel, a signal pad connected to the signal line, and a plurality of insulating layers disposed on the base layer. The signal pad includes a first conductive pattern connected to an end portion of the signal line, a second conductive pattern connected to the first conductive pattern, and at least one insulating pattern disposed between the end portion of the signal line and the second conductive pattern in a cross-sectional view and overlapping the second conductive pattern in a plan view.
