PROBLEM TO BE SOLVED: To improve the luminous intensity of the display light when lighted on, and achieve good white color balance. SOLUTION: The vertical sectional shape of each barrier rib 231, 232, 233, 234 is formed so that the first to the third top part intervals TDB, TDG, TDR may be the same value and that the first bottom part interval BDB may be greater > the third bottom part interval BDR > the second bottom part interval BDG. Thereby, the phosphor installation area of each color becomes smaller in order of blue > red > green.
