PROBLEM TO BE SOLVED: To reduce discharge deterioration of blue phosphors by constituting each pixel with four discharge cells comprising a red one, a green one, and two blue ones, and performing color display by controlling the lighting of these four discharge cells. SOLUTION: Phosphor layers G1, B1a, R1, B1b, G2, B2a, R2, B2b,..., are disposed in this order, a first pixel P1 is made up of four sub-pixels G1, B1a, R1, B1b, and a second pixel P2 is made up of G2, B2a, R2, B2b. For a certain period of time, for example for the first one year, display is performed by the first pixel P1 comprising three sub-pixels G1, B1a, R1, and by the second pixel P2 comprising three sub-pixels G2, B2a, R2, and during this period, the phosphor layers B1b, B2b are not lighted but are left inactive. For the next one year, display is performed by the first pixel P1' comprising three sub-pixels R1, B1b, G2, and by the second pixel P2' comprising three sub-pixels R2, B2b, G3, and during this period, the phosphor layers B1a, B2b, are not lighted but are left inactive. This enables aging deterioration of the blue phosphors to be reduced.
