Abstract

A display device includes a display panel including an antireflection layer on a light emitting element layer which includes a first pixel defining layer in which an opening defining a light emitting area of a first pixel is defined, and a second pixel defining layer in which an opening defining a light emitting area of a second pixel is defined. The antireflection layer includes first and second light blocking layers respectively overlapping the first and second pixel defining layers, and includes a first gap defined by a length of a predetermined direction from an edge of the opening to an edge of an opening of the first light blocking layer, and a second gap defined by a length from an edge of the opening to an edge of an opening of the second light blocking layer in the predetermined direction. The first gap is less than the second gap.

Dependent claims

A display device comprising:

a display panel including a first area in which first pixels are defined and a second area in which second pixels are defined;
the display panel comprising:
a light emitting element layer including a first pixel defining layer defining a light emitting area of the first pixel;
a thin film encapsulation layer covering the light emitting element layer;
a sensing layer disposed on the thin film encapsulation layer, and including:
sensing electrodes;
a first insulating layer;
a second insulating layer disposed on the first insulating layer;
and
a planarization layer disposed between the first insulating layer and the second insulating layer;
and
an antireflection layer disposed on the sensing layer and including a first light blocking layer overlapping the first pixel defining layer;
and
an under panel sensor overlapping the first area in a thickness direction,
wherein
a width of the first light blocking layer in a predetermined direction is less than a width of the first pixel defining layer in the predetermined direction, and
a thickness of the thin film encapsulation layer of the first pixel is less than a thickness of the thin film encapsulation layer of the second pixel.
