Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 5:
6. A display device comprising:
a substrate;
a transistor on the substrate;
a light emitting device connected to the transistor;
a power line connected to the transistor and the light emitting device;
an encapsulation layer covering the light emitting device;
sensing electrodes on the encapsulation layer; and
sensing lines on the encapsulation layer, the sensing lines being connected to the sensing electrodes,
wherein:
each of the sensing lines is formed as a multilayer structure;
in a direction normal to a surface of the substrate, a width of each multilayer structure varies between a first width and a second width different from the first width; and
first widths of the sensing lines are different from one another,
wherein the light emitting device comprises:
a first electrode connected to the transistor;
an emitting layer on the first electrode; and
a second electrode on the emitting layer, and

wherein, in the direction normal to the surface of the substrate, the second electrode fully overlaps all portions of the sensing lines such that the second electrode prevents voltages applied to the transistor from interfering with the sensing lines.
