Abstract
A vacuum fluorescent display apparatus includes semiconductor chips and a phosphor layer. The semiconductor chips are disposed on a glass substrate and having semiconductor integrated circuits formed thereon. The phosphor layer includes phosphor pixels driven by the semiconductor integrated circuits and arranged on the semiconductor integrated circuits in a matrix with the same space in horizontal and vertical directions. A space between first and second arrays of the phosphor pixels that are formed on end portions of opposing sides of first and second semiconductor chips arranged adjacent to each other becomes equal to a space among the phosphor pixels arranged on the semiconductor integrated circuits.
