Abstract

Of three primary color phosphors (38) formed in unit luminescent areas (EU) constituting a pixel (EG), the width of a blue phosphor (38B) is about twice the width of red and green phosphors (38R, 38G). This allows a white color temperature of 9300 K without causing deterioration of the phosphors (38) and degrading red and green gradations.
