Abstract
A liquid crystal display includes a pair of substrates having a polarizer, a liquid crystal layer sandwiched between the substrates of the pair, a color filter layer sandwiched between one of the substrates of the pair and the liquid crystal layer, a light source for supplying light to the pair of substrates, the liquid crystal layer, and the color filter layer. The color filter layer includes three filters for displaying blue, green and red. Only the green filter of the three filters selectively includes an absorbing component capable of absorbing a light spectrum within a wavelength range from 480 nm to 500 nm.
