Abstract

A display device includes: a substrate including a display region including a plurality of pixel regions, and a non-display region at a periphery of the display region; a pixel circuit layer including a plurality of circuit elements in the display region; a display element layer including a plurality of light emitting devices in the display region on the pixel circuit layer; and first and second alignment lines in the non-display region, the first and second alignment lines each having a multi-layered structure. Each of the first and second alignment lines includes: a main line in a same layer as at least one electrode in the display element layer; and at least one sub-line electrically connected to the main line, the at least one sub-line in a same layer as at least one electrode in the pixel circuit layer.
