The invention provides a plasma display filtering plate which comprises a light transmitting substrate LO, a coating overlapped body coated on the light transmitting substrate LO, a titanium dioxide coating (11-1) coated on the coating overlapped body, a light transmitting substrate LO' coated on the titanium dioxide coating (11-1), a metal film contacting with the coating and used as a led-out electrode, and a film layer or a glue layer compounded or melted together with the light transmitting substrate LO or the light transmitting substrate LO', wherein the film layer or the glue layer is made by adding absorbing dye and has maximum absorbing peak valleys of yellow characteristic of 580nm to 600nm. The invention has the functions of display emitting color regulation, electromagnetic isolation (EMI), near infrared light cut (NIR-cut), Ne characteristic light cut (Ne-cut), light transmittance improvement, and the contrast of the plasma display, can be overlapped with most of other methods of contrast improvement without high disturbance and enables the high contrast of the original psalm display to be increased again. The invention also provides a psalm display using the filteringplate.
