We have developed a mobile display using wide‐color‐gamut(WCG)‐white‐LEDs. An LCD with WCG‐white‐LEDs has almost the same color gamut (103% u'v'diagram) as that with WCG‐CCFLs developed by Sony. A red‐emitting‐phosphor with the longer luminescent wavelength should be used in WCG‐white‐LED to achieve WCG, because of the emission originated from 4f‐5d transition.
