A display device includes an emission area and a subarea located at a side of the emission area in a first direction, a first electrode extending in the first direction across the emission area and the subarea, a second electrode spaced from the first electrode in a second direction, the second electrode extending in the first direction, a first insulating layer on the first and second electrodes, the first insulating layer including an opening in the subarea, a plurality of light-emitting elements located on the first and second electrodes in the emission area, and a second insulating layer on the first insulating layer in the subarea, wherein the first electrode includes a first electrode extension located in the subarea at a first contact hole, the opening overlaps with the first contact hole and is located above the first electrode extension, and the second insulating layer overlaps the opening.

Display device

A display device includes conductive layers on a substrate, a via layer on the conductive layers, a first electrode and a second electrode extending in one direction on the via layer and spaced from each other, a first insulating layer on the first electrode and the second electrode, a plurality of light emitting elements on the first insulating layer, each of the light emitting elements having one end on the first electrode and an other end on the second electrode, and a first connection electrode and a second connection electrode on the first insulating layer, the first connection electrode overlapping the first electrode, and the second connection electrode overlapping the second electrode, wherein the first connection electrode and the second connection electrode are in contact with the conductive layers through contact portions.

A method of manufacturing a display device including: preparing a substrate having a display area and a non-display area; and forming an alignment mark disposed in the non-display area of the substrate. The alignment mark includes a quadrangular-shaped center portion and a plurality of measurement portions that surround the center portion, the plurality of measurement portions including four or more measurement portions, and each of the measurement portions including sides that are parallel with two sides of the quadrangular-shaped center portion.

Display device and manufacturing method thereof

A display device includes a first substrate including a first side surface, a display area, and a pad area located outside of the display area and adjacent to the first side surface, a second substrate facing the first substrate and including a second side surface extending further outward than the first side surface of the first substrate, a printed circuit board electrically connected to the pad area of the first substrate and bent along the first side surface of the first substrate, and a light blocking chassis overlapping the printed circuit board and the first side surface of the first substrate.

An exemplary embodiment provides a display device including: a display part configured to include a display part color filter; and a peripheral part disposed at the upper side of the display part and including an inspection pattern for checking an alignment of the display part color filter. The inspection pattern may include a plurality of color filters having colors and reference patterns disposed at at least one side of the plurality of color filters. A number of the plurality of color filters of each color corresponds to a number of shots of a division exposure process. Adjacent color filters among the plurality of color filters may be disposed at different heights.

A display device including: a substrate having display area and a non-display area; and an alignment mark disposed in the non-display area of the substrate. The alignment mark includes a quadrangular-shaped center portion and a plurality of measurement portions that surround the center portion, the plurality of measurement portions including four or more measurement portions, and each of the measurement portions including sides that are parallel with two sides of the quadrangular-shaped center portion.
