    Abstract: A display panel with microcavities each having ends of asymmetric cross-sectional area. An exemplary display panel has a substrate; a pixel electrode formed on the substrate; a first black matrix and a second black matrix each disposed on the substrate; and a supporting member disposed on the substrate over the pixel electrode and the black matrix, the supporting member shaped so as to form a microcavity between the pixel electrode and the supporting member, the microcavity having an upper surface proximate to the supporting member and a lower surface opposite the upper surface. The microcavity has one end positioned over the first black matrix, and another end opposite the first end and positioned over the second black matrix; the lower surface of the microcavity has first and second channels disposed therein, the first channel positioned over the first black matrix, and the second channel positioned over the second black matrix.

    Abstract: A display device includes: a first electrode and a second electrode spaced apart from each other; first and second light emitting elements between the first electrode and the second electrode; a first contact electrode contacting the first electrode and a first end portion of the first light emitting element; a second contact electrode contacting a second end portion of the first light emitting element; a third contact electrode contacting the second contact electrode and a first end portion of the second light emitting element and overlapping the first electrode; and a fourth contact electrode contacting a second end portion of the second light emitting element and overlapping the second electrode. The first contact electrode and the third contact electrode are on the same layer.

    Abstract: A display device includes a pixel in a display area. The pixel includes: a first electrode and a second electrode spaced from each other; a light emitting element between the first electrode and the second electrode, a first bank overlapping with one area of each of the first electrode and the second electrode in a plan view, the first bank including a first sidewall adjacent to the first end portion of the light emitting element and a second sidewall adjacent to the second end portion of the light emitting element; at least one of a third electrode on the first end portion of the light emitting element to connect the first end portion to the first electrode and a fourth electrode on the second end portion to connect the second end portion of the light emitting element to the second electrode.
