Abstract

A display device includes a substrate including a first area, a second area, and a bending area. A plurality of first wires are positioned in the first area. A plurality of second wires are positioned in the second area. An insulating layer is positioned in the bending area. A plurality of connecting wires are disposed on the insulating layer. Each of the connecting wires is connected with at least one of the first wires and at least one of the second wires. Each of the connecting wires includes a first portion and a second portion alternatingly arranged along an extending direction of the connecting wires. A width of the first portion is wider than a width of the second portion in a direction perpendicular to the extending direction each of the connecting wires.
