发明名称 FILTER AND PLASMA DISPLAY DEVICE THEREOF
摘要 The present invention relates to a plasma display device, and a filter formed in a plasma display panel includes an external light shielding sheet which includes a base unit, and a plurality of pattern units that are formed on the base unit, wherein an angle between an electrode that is formed on the substrate adjacent to the filter and the pattern unit is 5° or less. According to the present invention, the plasma display device can effectively realize black images and enhance bright room contrast, as an external light shielding sheet, which absorbs and shields as much external light incident upon a plasma display panel PDP as possible, is disposed at a front of the plasma display panel. In addition, the plasma display device of the present invention may reduce the moire phenomenon, as the patterns of the external light shielding sheet is diagonally formed at an angle with the electrode or the barrier rib formed in the panel.
