Selfluminous display device having light emission sources having substantially non-overlapping spectra levels

Abstract

A selfluminous display device having distinct blue (B), green (G) and red (R) light emission sources wherein the spectra of the light emission sources each have a narrow half band width (30 nm or less) at a level regarded as precursor delta functions, which do not mutually substantially overlap. Because light sources having spectra of limited peak values and extremely narrow limited widths are used, shape changes of the spectrum in each light source are suppressed in the wavelength space and can be regarded as purely magnitude changes. Therefore, it becomes possible to correct just by changing the strength for each light emission source, color reproducibility increases and there ceases to be any change over time in the colors.
