Abstract

An electronic apparatus includes a substrate, a first region in which a plurality of pixels are provided on the substrate and that has a first side, a second side, a third side, a fourth side, and a plurality of curved line parts, and a second region positioned between an end part of the substrate and the first region.

Claims (25)

1. An electronic apparatus comprising:

a substrate;

a first region in which a plurality of pixels are provided on the 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 substrate and the first region;

a plurality of signal lines;

an organic insulating film covering the signal lines;

a signal-line coupling circuit disposed in the second region and coupled to the signal lines;

a plurality of wires coupling the signal-line coupling circuit to a plurality of terminals arrayed in the second region;

a first shield layer that is provided above the organic insulating film near at least one of the curved line parts, covers at least part of the signal-line coupling circuit, the wires, and the signal lines, and is provided with a plurality of openings;

a second shield layer covering the openings;

a plurality of scan lines intersecting the signal lines;

at least one gate driver disposed in the second region and coupled to the scan lines; and

an ion trapping electrode provided between the first shield layer and the gate driver and between the second shield layer and the gate driver near at least one of the curved line parts and supplied with constant potential.

2. The electronic apparatus according to claim 1 , wherein

the signal lines, a plurality of sensor wires, a plurality of first electrodes, and a plurality of second electrodes are layered in order in the first region with an insulating film interposed between layers,

the sensor wires electrically couple the terminals to the first electrodes,

the second electrodes are partitioned by the pixels,

the first shield layer is provided in the same layer as the first electrodes, and

the second shield layer is provided in the same layer as the second electrodes.

3. The electronic apparatus according to claim 1 , wherein the second shield layer includes

a plurality of shield parts arrayed at intervals, and

a coupling part through which the shield parts adjacent to each other are coupled.

4. The electronic apparatus according to claim 1 , wherein the plurality of second shield layers are supplied with the same potential as the first shield layer.

5. The electronic apparatus according to claim 1 , wherein the ion trapping electrode is provided in the same layer as the second shield layer and overlaps with neither the first shield layer nor the second shield layer in a plan view.

6. The electronic apparatus according to claim 1 , further comprising a third shield layer covering the gate driver and provided in the same layer as the second shield layer and the ion trapping electrode.
