Abstract
An liquid crystal display including a backlight module and an LCD panel is disclosed. The backlight module has a white light source, and the normalized optical spectrum of the backlight module is BL(λ). The LCD panel includes a red color filter layer, a green color filter layer and a blue color filter layer. The green color filter layer and the backlight module are subject to the following relationship: E=C/D and E≧0.8, wherein A is defined as the wavelength corresponding to the maximum peak value of CF(λ)×BL(λ)×x(λ); B is defined as the wavelength corresponding to the maximum peak value of CF(λ)×BL(λ)×y(λ); C is defined as the integral on CF(λ)×BL(λ)×x(λ) over the interval between A and B; D is defined as the integral on CF(λ)×BL(λ)×y(λ) over the interval larger than B, CF(λ) is the transmission spectrum of the green color filter layer; and x(λ) and y(λ) are color matching functions.
