Abstract
A display apparatus includes a first base substrate (BS), a second BS facing the first BS, a liquid crystal layer disposed between the first BS and the second BS, a color filter layer, pixel electrodes, a light-shielding column spacer, a common electrode, and trap electrodes. The first BS includes a display area and a non-display area. The color filter layer is disposed on the first BS in the display area. The pixel electrodes are disposed on the color filter layer. The light-shielding column spacer is disposed on the first BS in the non-display area and includes a light-shielding material. The common electrode is disposed on the second BS and faces the pixel electrodes. The liquid crystal layer is disposed between the common electrode and the pixel electrodes. The trap electrodes are disposed on a lower portion of the light-shielding column spacer and face the common electrode.
