摘要： PROBLEM TO BE SOLVED: To provide an FED (field emission display) in which a desirable white color temperature is attained without deteriorating white uniformity and brightness.
SOLUTION: The width WG of a green phosphor 22 is set larger than the width WR of a red phosphor 21 or the width WB of a blue phosphor 23, and the distance PRG between the center of the red phosphor and the center of the green phosphor is set larger than the distance PBR between the center of the blue phosphor and the center of the red phosphor. Thus, the width WBM of a black matrix between the phosphors is made constant. At the same time, an electron source is arranged to correspond to the phosphors. Thus, a desirable white color temperature is attained without deteriorating the landing tolerance of an electron beam and the utilization efficiency of the phosphor surface.
