摘要:
A liquid crystal display apparatus includes a liquid crystal panel having polarizers, and a back light having a light source for illumination of the liquid crystal panel which has a characteristic of spectral transmittance required to satisfy the following equation, x>y>z, when a medium tone display voltage varies in a range between a minimum and maximum voltage for a Blue pixel, where “x” is a value of the transmittance in the panel at a wavelength corresponding to a longest wavelength in a range of wavelengths designated for blue light, “y” is a value of the transmittance in the panel at a wavelength corresponding to a maximum value of the intensity in a range of wavelengths designated for green light, and “z” is a value of the transmittance in the panel at a wavelength corresponding to a maximum value of the intensity in a range of wavelengths designated for red light.
