    Abstract: A display device includes a substrate including a plurality of pixels disposed in a display area of the substrate. A non-display area of the substrate is disposed adjacent to the display area. The display device further includes a plurality of gate lines and a plurality of data lines arranged in a matrix form in the display area on the substrate, at least one driver integrated circuit (IC) disposed in the non-display area on the substrate, and a plurality of data fan-out wirings disposed on the substrate and connecting the data lines and the at least one driver IC. Lengths of the data fan-out wirings vary, and the data lines overlap the gate lines more as the lengths of the corresponding data fan-out wirings decrease.

    Abstract: A display device includes: a display substrate including a display area and a non-display area adjacent to each other; and an opposing substrate opposing the display substrate. The display substrate includes: a pixel in the display area; a gate driver at the non-display area and including a gate and data wiring; an organic layer on the gate and data wiring; a column spacer on the organic layer; a connection portion connected to the gate and data wiring at contact holes respectively exposing the gate and data wiring; and a protective layer on the connection portion. In a top plan view, the protective layer has a same shape as a shape of the connection portion. The opposing substrate includes a black matrix at the display area to define a pixel area of the pixel and at the non-display area to define the display area and the non-display area.
