Patent ID: 7839088

Claim:
A display panel comprising a dielectric layer that contains a glass composition and covers an electrode, wherein the glass composition is an oxide glass composition, having a composition satisfying: 60 wt %<B 2 O 3 <78 wt %, 15 wt %≦ZnO≦24 wt %, 6 wt %≦R 2 O≦16 wt % 1 wt %≦MO<17 wt %, and 0 wt %≦SiO 2 ≦10 wt %, where R denotes at least one selected from Li, Na, and K, and M indicates at least one selected from Mg, Ca, Sr, and Ba, wherein the class composition has a softening point of 590° C. or lower, a glass transition point of at least 475° C. a thermal expansion coefficient of 60×10 −7 /° C. to 90×10 −7 /° C., and a relative permittivity of 6.5 or lower.
