Abstract: A display panel includes a support substrate including a display area having a plurality of pixel areas and a non-display area disposed around the display area. An encapsulation substrate faces a first side of the support substrate. An emitting array is disposed on the first side of the support substrate. A phase adjusting layer is disposed on the emitting array and changes a phase of light. A reflected light absorbing layer is disposed on the phase adjusting layer and absorbs at least a portion of light reflected from the emitting array. A sealing layer is disposed in the non-display area between the support substrate and the encapsulation substrate. A black matrix layer is disposed on a first side of the encapsulation substrate and corresponds to boundaries between the plurality of pixel areas.

Abstract: According to some embodiments of the present disclosure, a display device includes: a substrate; a planarization layer on the substrate; a first alignment mark in a non-display area of the substrate; a first electrode and a second electrode in a display area of the substrate; a light emitting element electrically connected to the first electrode and the second electrode; a wavelength conversion layer on the light emitting element; a first bank on at least a part of the first electrode; and a second bank on the first bank to be around the wavelength conversion layer. A thickness of a part of the planarization layer that overlaps the first alignment mark in a thickness direction of the substrate is greater than a thickness of a part of the planarization layer that overlaps the first electrode and the second electrode in the thickness direction of the substrate.
