Abstract: PROBLEM TO BE SOLVED: To restrain halation to provide a high bright color image by coloring the image, which keeping the difference between the transmissivity in the wavelength range of a blue phosphor and that in the wavelength range of a red phosphor to be more than a specific value. SOLUTION: By adding a colorant to a glass board for reducing the transmissivity in the visible wavelength range, and improving absorption of light scattering on the inner surface of a front surface glass board, halation is restrained. For this, the transmissivity is adjusted so as to satisfy the relation, T%460 -T%620 >=4, where T%460 is the transmissivity in the wavelength range of a blue phosphor, λ=460 nm and T%620 is the transmissivity in the wavelength range of a red phosphor, λ=620 nm, lack of light emission efficiency of the blue phosphor is compensated, and therefore reduction in the brightness is prevented. Most suitable range is 8>=T%460 -T%620 >=5. CoO and NiO are added together as a colorant into a glass composition. The adequate ranges of the both are 20-200 ppm for CoO and 60-140 ppm for NiO.
