Abstract
A display apparatus includes a plasma display panel (PDP) and a filter having a panel side facing a display surface of the PDP and an opposing viewer side facing away from the display surface. The filter includes an external light shield having a first base unit and first pattern units. The first pattern units absorb external light from the viewer side and are substantially parallel to a first axis. The filter includes an electromagnetic interference (EMI) shield overlapping the external light shield. The EMI shield includes a second base unit and second pattern units. The second pattern units are conductive and substantially parallel to a second axis. An interior angle between the first axis and the second axis can be within a range of 40 to 50 degrees.
