PROBLEM TO BE SOLVED: To provide an image display apparatus capable of obtaining proper white balance. SOLUTION: An inner surface filter 4R and an inner surface filter 4B are placed in between a glass panel 1 and the fluorescent screens of red phosphors 3G and in between the glass panel and the fluorescent screens of blue phosphors 3B, respectively. This gives a red color chromaticity (x, y) of (0.656, 0.343), and a blue color chromaticity of (0.146, 0.063). A brightness ratio among red, green, and blue is given as R:G:B=306:1150:159. When a white color chromaticity (x, y) is determined as being (0.283, 0.298) (=color temperature 9,300 K) and white brightness is determined as being 200 cd/m<SP>2</SP>, the current density ratio for light emission for each color is given by R:G:B=65:100:98.
