摘要：
A plasma display device is provided. The plasma display device includes a plasma display panel (PDP) and an external light shield sheet which absorbs external light incident upon the PDP. The external light shield sheet includes a base unit and a plurality of pattern units which are formed in the base unit. Each of the pattern units contains 2-10 weight % of light absorption particles having a size of 1 μm or less. Since the external light shield sheet which can absorb and shield as much external light as possible is disposed at the front of the PDP, the plasma display device can effectively realize black images and improve bright room contrast.
