Abstract
A display device where it is possible to prevent dark spots by aligning the light emitting elements through a primary alignment process followed by a secondary alignment process to evenly distribute the light emitting elements, and to secure overlapping connections and prevent a voltage drop by electrically connecting all alignment lines to high potential lines and low potential lines having a mesh structure after the alignment process is completed.
