Abstract: A display apparatus may include a backlight assembly configured to generate an emitted light and a display panel configured to receive the emitted light to display images. The display panel may include a display substrate, an opposite substrate facing the display substrate, a wire grid polarizer, and a reflection reducing layer. The wire grid polarizer may be disposed on at least one of the display substrate and the opposite substrate to polarize the emitted light. The reflection reducing layer may have a grid shape and may be disposed on the wire grid polarizer. The reflection reducing layer may reduce an amount of a light reflected by the wire grid polarizer.
