Abstract
An image display apparatus has a plurality of phosphor films two-dimensionally disposed on a substrate, a matrix-pattern rib formed on the substrate to partition between the phosphor films, a plurality of metal backs each covering at least one phosphor film, and resistance wirings having a sheet resistance higher than that of the metal backs for electrically connecting the plurality of metal backs to each other. The resistance wirings are disposed to the apexes of the matrix-pattern rib and composed of a plurality of column lines and a plurality of row lines, the metal backs have first portions for covering the phosphor films on the substrate and second portions formed along the rib to connect the first portions to the column lines.
Claims4
An image display apparatus comprising:
- a plurality of phosphor films two-dimensionally disposed on a substrate;
- a matrix-pattern rib formed on the substrate to partition the phosphor films;
- a plurality of metal backs each covering at least one phosphor film;
- and
- resistance wirings which have a sheet resistance higher than that of the metal backs, and electrically connect the plurality of metal backs to each other,
- wherein the resistance wirings are disposed to apexes of the matrix-pattern rib and composed of a plurality of column lines and a plurality of row lines,
- the metal backs have first portions covering the phosphor films on the substrate and second portions formed along the rib to connect the first portions to the column lines, and
- a width of the second portions in a column direction at the apexes of the rib is smaller than a width of the first portions in the column direction.
