Abstract
The invention is to offer a glass-break preventing film like filter to be directly attached to a visual side of a plasma display plate, so that no problem occurs of double images caused owing to an air layer, contributing to easy attachment, light weighing, thin size and low cost, and a plasma display apparatus attached with the same. A glass-break preventing film like filter is composed by laminating a reflection preventing film on one side of a glass-break-preventing layer comprising a composite material of a transparent organic high polymer substance and an organized layer like clay, and making the other side an adhesive face, and a plasma display apparatus is composed by directly attaching on a visual side thereof with the glass-break preventing film like filter via the adhesive face of the glass-break preventing layer.
