Abstract: A display device includes a display element layer on a substrate. The display element layer may include first and second electrodes, and light emitting elements electrically coupled to the first and second electrodes. The first electrode may include first protrusions, a first portion located between the first protrusions, a second portion corresponding to a side of each first protrusion, and a third portion coupled between the first portion and a first end of the second portion. The second electrode may include second protrusions that protrude toward the first electrode and are spaced apart from each other in the first direction, a first portion located between the second protrusions, a second portion corresponding to a side of each of the second protrusions, and a third portion coupled between the first portion and a first end of the second portion.

Abstract: A display device includes: a first substrate; a second substrate on the first substrate and exposing a first edge portion of the first substrate, the second substrate protruding beyond a second edge portion of the first substrate; a connection line on the first edge portion of the first substrate, the connection line having a first end portion protruding beyond a first side of the second substrate and a second end portion covered by the second substrate; and a thin-film transistor layer on the second substrate and connected to the connection line. The thin-film transistor layer includes signal lines extending from the first side to a second side of the second substrate. The signal lines extend into contact openings in the thin-film transistor layer and are exposed at a lower part of the second substrate on the second side of the second substrate.
