A plasma display panel has a front substrate, a rear substrate, and a phosphor layer. The front substrate has a dielectric layer formed so as to cover a plurality of display electrodes disposed on a substrate, and a protective layer formed on the dielectric layer. The rear substrate is faced to the front substrate so as to form discharge space, has data electrodes in the direction intersecting with the display electrodes, and has barrier ribs for partitioning the discharge space. The phosphor layer is formed by applying phosphor ink that is made of a phosphor material and dispersant between the barrier ribs of the rear substrate. Nano-particles with a diameter of a range of 1 nm to 100 nm inclusive, or a solvent having an affinity for the dispersant of the phosphor ink is applied to the surfaces of the barrier ribs, and then the phosphor ink is applied to them, thereby forming the phosphor layer.

This invention provides a light absorber which can be used for optical equipment like optical-disk equipment and a liquid crystal display. The light absorber has a layered structure including a light absorbing layer and a transparent layer. The light absorbing layer absorbs a reflected light from the inside of the absorber as well as incident light into the absorber while the transparent layer helps attenuate the reflected light by interference of light. One of the light absorbing layers which is thicker than others may work as a shading layer for the incident light.
