<p>Disclosed is a phosphor for displays which is mainly composed of a ternary compound phosphor activated by Ce or Eu and emits light when excited by an electron beam having an acceleration voltage of not more than 15 kV. This phosphor for displays is characterized in that the first element constituting the ternary compound is at least one element selected from Na, Ba, Sr and Ca, the second element is Y or Si, and the third element is S. This phosphor has high color purity and improved emission luminance. By using such a phosphor, there can be realized a thin flat display having high luminance and excellent display characteristics such as color reproduction.</p> |
