Abstract:
1. A liquid crystal display, comprising: a backlight module having at least a white light source, wherein a normalized optical spectrum of the backlight module is BL(λ), and a liquid crystal display panel disposed over the backlight module and comprising two substrates and a liquid crystal layer located between the substrates, wherein one of the substrates has a red color filter layer, a green color filter layer and a blue color filter layer, and the green color filter layer and the backlight module are subject to the following relationship: wherein A is defined as the wavelength corresponding to the maximum peak value of CF Green (λ)×BL(λ)×x(λ); B is defined as the wavelength corresponding to the maximum peak value of CF Green (λ)×BL(λ)×y(λ); C is defined as the integral on CF Green (λ)×BL(λ)×x(λ) over the interval between A and B; D is defined as the integral on CF Green (λ)×BL(λ)×y(λ) over the interval larger than B; CF Green (λ) is the transmission spectrum of the green color filter layer, and x(λ) and y(λ) are color matching functions.
