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