Abstract: Disclosed are embodiments of a narrow bezel display. The narrow bezel display has a structure in which output terminals of gate circuits are connected to jumping units through wires having a multistage path, thereby reducing the bezel size of a display. A dielectric layer may be disposed under the multistage path without placing another wire layer thereunder to prevent non-uniform capacitance between the wires and an underlying wire layer. Thus, a dimming phenomenon may be prevented during operation of the display or a short circuit may be prevented during an electrostatic test.
