Abstract
The present invention improves discharge characteristics of a protective layer in order to provide a PDP that exhibits excellent display performance even if the PDP is of a fine-cell structure. The present invention also provides a manufacturing method for the PDP. In particular, a protective layeris composed of an MgO film layerand an MgO particle layerthat is made of MgO particles. The MgO particlesare formed by burning an MgO precursor and satisfy that a/b≧1, where a denotes a spectrum integral value in a wavelength region of a CL spectrum from 200 nm to 300 nm, exclusive of 300 nm, and b denotes a spectrum integral value in a wavelength region of the CL spectrum from 300 nm to 550 nm, exclusive of 550 nm.
