A 34-inch inorganic EL panel for a high-definition TV with a simple structure has been successfully developed by combining color-conversion materials and BaAl_2S_4: Eu blue phosphor. The luminance and maximum efficacy of the blue phosphor devices are higher than 2,300cd/m^2 for applied AC voltage of threshold-voltage plus 60V at operation frequency of 120Hz and 2.5lm/W, respectively. The panels, which were fabricated using these technologies, achieved a peak luminance of over 400cd/m^2, a color gamut of larger than 95% of the NTSC color area in CIE (x, y), and a wide viewing angle.
