Abstract

A display panel includes a base layer, a circuit layer disposed on the base layer, a light-emitting element layer disposed on the circuit layer and including a light-emitting element having a pixel electrode, a light-emitting layer disposed on the pixel electrode, and a common electrode disposed on the light-emitting layer, an encapsulation layer disposed on the light-emitting element layer, and a pattern disposed between the circuit layer and the light-emitting element layer. At least a portion of the pattern may be disposed in a region adjacent to the light-emitting element, with respect to a plan view of the display panel.

Claims20

Dependent claims

A display panel comprising:

a base layer;
a circuit layer disposed on the base layer;
a light-emitting element layer disposed on the circuit layer, and including a light-emitting element having a pixel electrode, a light-emitting element layer disposed on the pixel electrode, and a common electrode disposed on the light-emitting layer, and a pixel defining pattern disposed on the pixel electrode and having and having an opening defined therein to expose a portion of the pixel electrode;
an encapsulation layer disposed on the light-emitting element layer;
and
a pattern disposed between the circuit layer and the light-emitting element layer, wherein
at least a portion of the pattern is disposed in a region adjacent to the light-emitting element, with respect to a plan view of the display panel, and
the pixel defining pattern covers another portion of the pixel electrode that entirely overlaps the pattern.

5 more elements

An electronic device comprising a display panel in which an auxiliary display region having an element region and a transmission region defined therein, and a main display region adjacent to the auxiliary display region are defined,

wherein the display panel includes:
a base layer;
a circuit layer disposed on the base layer;
a phase shift pattern disposed on the circuit layer and disposed in the auxiliary display region;
a first light-emitting element disposed in the auxiliary display region and including a first pixel electrode disposed on the phase shift pattern;
and
a second light-emitting element disposed in the main display region and including a second pixel electrode disposed on the circuit layer, wherein
the first pixel electrode overlaps the element region, and at least a portion of the phase shift pattern overlaps the transmission region, and
an entire edge of the first pixel electrode is surrounded by the at least a portion of the phase shift pattern, with respect to a plan view of the display panel.
