Plasma display panel
View Patent ↗A PDP ( 101 ) with a reduced discharge inception voltage and discharge sustaining voltage for improving luminous efficiency has at least a pair of substrates ( 110 and 111 ) that are disposed in opposition to sandwich a discharge space therebetween. At least a portion of at least one of the substrates has two or more display electrode pairs ( 104 ) that include narrow bus electrodes ( 159 and 169 ), a dielectric layer ( 107 ) formed so as to cover the display electrode pairs ( 104 ), and a protective layer ( 108 ) formed so as to cover the dielectric layer ( 107 ). The dielectric layer ( 107 ) has a dense film structure with a dielectric breakdown voltage of 1.0×10 6 [V/cm] to 1.0×10 7 [V/cm].
