Patent ID: 7528902

Claim:
A liquid crystal display, comprising: a cold cathode fluorescent lamp including a red phosphor, a green phosphor and a blue phosphor and emitting white light, the green phosphor including BaMgAl 10 O 17 :Eu, Mn and the blue phosphor including BaMgAl 10 O 17 :Eu; and a liquid crystal panel modulating the white light according to an image signal to emit the modulated white light as a display light, wherein assuming that the maximum peak intensity is Pbmax, the peak intensity at a wavelength of 506 nm is Pb(506 nm), the peak intensity at a wavelength of 530 nm is Pb(530 nm), and the peak intensity at a wavelength of 550 nm is Pb(550 nm), in blue spectral characteristics of the display light, Pbmax, Pb(506 nm), Pb(530 nm) and Pb(550 nm) satisfy the following conditional expressions (1) through (3): Pb (506 nm)/ Pb max≦0.550 (1) Pb (530 nm)/ Pb max≦0.100 (2) Pb (550 nm)/ Pb max≦0.025 (3).
