    • A plasma display panel is provided with a front board (2) wherein a dielectric layer (8) is formed to cover a display electrode (6) formed on a front glass substrate (3) and a protection layer (9) is formed on the dielectric layer (8); and a back board, which faces the front board (2) so as to form a discharge space, forms an address electrode in a direction intersecting with the display electrode and has a partitioning wall for partitioning the discharge space. The protection layer (9) forms a base film (91) on the dielectric layer (8) and is constituted by adhering agglomerated particles (92) wherein a plurality of crystal grains composed of a metal oxide are agglomerated, on the base film (91) so that the agglomerated particles are distributed over the entire surface. The agglomerated particles are adhered so that the ratio of the transmissivity of the front board (2) with the agglomerated particles (92) adhered thereto to the transmissivity of said front board without the agglomerated particles adhered thereto is 85% or more but not more than 99%. Thus, the PDP, which has improved electron discharge characteristics, charge retention characteristics, and achieves high image qualities, low cost and low voltage at the same time, is provided.
    • 等离子体显示面板设置有前板(2),其中形成介电层(8)以覆盖形成在前玻璃基板(3)上的显示电极(6),并且保护层(9)形成在 电介质层(8); 以及面向前板(2)以形成放电空间的背板,在与显示电极相交的方向上形成寻址电极,并具有用于分隔放电空间的分隔壁。 保护层(9)在电介质层(8)上形成基膜(91),由基底膜(91)上附着由多个由金属氧化物构成的晶粒聚集的凝集粒子(92) ),使得附聚颗粒分布在整个表面上。 凝聚的颗粒被粘合,使得前板(2)与附着于其上的附聚颗粒(92)的透射率与所述前板的透射率的比率不是附着在其上的凝聚颗粒的85%以上但不大于 99%。 因此,提供了具有改善的电子放电特性,电荷保持特性,同时实现高图像质量,低成本和低电压的PDP。
