1. A display device comprising:
a first substrate;
a transistor on the first 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; and
a sensor on the encapsulation layer,
wherein the sensor comprises:
sensing electrodes; and
sensing lines connected to the sensing electrodes,
wherein 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 a direction normal to a surface of the first 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.
