Abstract: A substrate for a display device includes a plurality of first lines on the substrate in a display area of the display device, a plurality of link lines on the substrate in a link region, the link lines electrically connected to the first lines and the link region being in a non-display area of the display device, an insulating layer on the first lines and the link lines, a plurality of second lines on the insulating layer, patterns on the insulating layer in the link region and at least partially overlapping the link lines, the patterns including an intrinsic semiconductor material, and a passivation layer on the second lines and the patterns, the passivation layer having at least one through hole exposing the intrinsic semiconductor material of at least one of the patterns.
