Abstract: A display substrate includes a base substrate, a switching device, and a pixel electrode including a first sub pixel electrode and a second sub pixel electrode. The first sub pixel electrode includes an internal electrode and an external electrode. The internal electrode includes a support electrode portion extending in a second direction, and a horizontal internal branch electrode portion extending in a first direction. The external electrode includes a horizontal external branch electrode portion disposed outside the internal electrode and extending in the first direction, and a vertical external branch electrode portion disposed outside the internal electrode and extending in the second direction. The second sub pixel electrode is adjacent to the first sub pixel electrode and has a shape symmetrical to the first sub pixel electrode.
