。[Problems to be Solved by the Invention] However, the phosphor film of conventional color display PDPs is formed by turning the phosphor into a powder and then printing or coating it as a paste. So,
There was a problem in that the phosphor film became white and opaque, and the light from the phosphor emitted inside the light-emitting cell was not efficiently transmitted to the outside, resulting in poor luminous efficiency. In addition, since the phosphor film was formed by printing or coating paste, it would be good if the phosphor film forming part of the front glass plate was flat, but it would be better to use it as a barrier to prevent color crosstalk or to increase luminous efficiency. When the phosphor film forming portion has an uneven surface shape, as in the case where recesses are formed, there is a problem in that it is difficult to form a phosphor film of a constant thickness. The present invention was made in view of the above-mentioned problems, and an object of the present invention is to provide a phosphor film for a color display PDP that can efficiently transmit the light of the phosphor emitted inside the light emitting cell to the outside. Another object of the present invention is to provide a method for forming a phosphor film for a color display PDP, which can form a transparent phosphor film of a constant thickness even when the phosphor film forming portion has an uneven surface shape. It is something.
