Abstract

A display device in an embodiment includes a first light emitting region; a second light emitting region located at a position away from the first light emitting region by a first distance in a first direction; a third light emitting region located at a position away from the second light emitting region by a second distance shorter than the first distance in the first direction; a first conductive portion located between the first light emitting region and the second light emitting region as seen from a display plane, the first conductive portion having a first width in the first direction, and a second conductive portion located between the second light emitting region and the third light emitting region as seen from the display plane, the second conductive portion having a second width shorter than the first width in the first direction.

Claims5

Dependent claims

A display device comprising:

a first light emitting element having a first light emitting region;
a second light emitting element having a second light emitting region;
a sealing layer covering the first light emitting element and the second light emitting element;
and
a plurality of sensor electrodes on the sealing layer, wherein
one of the plurality of sensor electrodes has a first opening at a portion corresponding to the first light emitting region, and a second opening at a portion corresponding to the second light emitting region,
an area of the first light emitting region and an area of the second light emitting region are different from each other,
an area of the first opening and an area of the second opening are different from each other, and
a distance between an edge of the first opening and an edge of the first light emitting region in a planar view and a distance between an edge of the second opening and an edge of the second light emitting region in the planar view are equal to each other.
