    • A plasma display apparatus having a structure capable of improving a light efficiency is disclosed. The reflecting mirror plane or a metal reflecting film is formed on a back surface of a back plate of the plasma display apparatus, so that the back face light is reflected more than 95%, and thus, the light loss due to the back face light can be minimized, so that the light efficiency of the plasma display apparatus can be heightened. Especially, by forming the reflecting film having almost the same diameter as that of the discharge cell and a predetermined curvature at the positions corresponding to the discharge cells on the rear plate of the plasma display apparatus, the light interference between the discharge cells due to the reflected light can be prevented. Also, since the reflecting film serves as a high frequency blocking film, the loss of high frequency of the high frequency plasma display apparatus can be prevented.
    • 公开了具有能够提高光效率的结构的等离子体显示装置。 反射镜面或金属反射膜形成在等离子体显示装置的背板的后表面上,使得背面光反射率大于95%,因此由背面光引起的光损失 可以最小化,从而可以提高等离子体显示装置的光效率。 特别地,通过在与等离子体显示装置的后板上的放电单元对应的位置处形成具有与放电单元几乎相同的直径的反射膜和预定的曲率,由于 可以防止反射光。 此外,由于反射膜用作高频阻挡膜,因此可以防止高频等离子体显示装置的高频损失。
