Abstract

A display device may include first, second, and third sub-pixels. Each of the first, second, and third sub-pixels may include: a pixel circuit layer including first, second, and third transistors disposed on a substrate, and a bridge pattern disposed on a gate electrode of the first transistor and a source electrode of the second transistor, a first end of the bridge pattern is electrically connected to the source electrode of the second transistor and a second end of the bridge pattern is electrically connected to the gate electrode of the first transistor; first and second alignment electrodes disposed on the pixel circuit layer; and light emitting elements disposed on the first and second alignment electrodes and electrically connected to at least one of the first, second, and third transistors. The second alignment electrode may be supplied with a low potential voltage and overlap the bridge pattern in a plan view.
