Abstract:
In a plasma display apparatus of the preset invention, a filter including an external light shielding sheet configured to shield externally incident light to the greatest extent possible is disposed at the front, thus effectively implementing a black image and improving the bright and dark room contrast. Furthermore, since the external light shielding sheet and an EMI shielding sheet are formed to be aligned, thereby sustaining the luminance of the screen.
