Display device with ion trapping electrodes

A display device comprising:

• an array substrate;
• a first region in which a plurality of scan lines extending in a first direction, a plurality of signal lines extending in a second direction, and a plurality of pixels are provided on the array substrate and that has a first side, a second side, a third side, a fourth side, and a plurality of curved line parts;
• a second region positioned between an end part of the array substrate and the first region;
• a signal-line coupling circuit disposed in the second region and coupled to the signal lines;
• a shield layer disposed in the second region and covering at least part of the signal-line coupling circuit near at least one of the curved line parts;
• a gate driver circuit disposed in the second region outside the signal-line coupling circuit and coupled to the scan lines;
• a first ion trapping electrode disposed between the shield layer and the gate driver circuit, provided in a linear shape along the gate driver circuit, and supplied with constant potential;
• a second ion trapping electrode disposed between the shield layer and the first ion trapping electrode, provided in a linear shape along an edge of the shield layer, and supplied with the same potential as the first ion trapping electrode;
• and
• a bifurcating electrode through which the second ion trapping electrode bifurcates from halfway through the first ion trapping electrode in the linear shape.
