FLUORESCENT LAMP, AND LIGHT EMITTING DEVICE AND DISPLAY DEVICE USING FLUORESCENT LAMP

摘要

Provided is a fluorescent lamp having a glass container. The glass container has a fluorescent film, which contains a fluorescent material, on an inner surface, and is hermetically sealed. The fluorescent material contains a blue fluorescent material, which has a main emission peak in a wavelength region of 430nm or more but not more than 460nm, and has a spectrum half-width of 50nm or less at the main emission peak; a green fluorescent material, which has a main emission peak in a wavelength region of 510nm or more but not more than 530nm, and has a spectrum half-width of 30nm or less at the main emission peak; and a red fluorescent material, which has an emission peak in a wavelength region of 600nm or more but not more than 780nm. The difference between the wavelength at the main emission peak of the blue fluorescent material and that at the main emission peak of the green fluorescent material is 70nm or more but not more than 90nm.
