Abstract
A liquid crystal display device has a light source unit and a liquid crystal cell sandwiched by two polarizing plates. The light emitted by the light source unit has separated peaks in each of blue, green and red wavelength ranges. The green and red peaks have a full width at half maximum intensity of 20 nm or more. At least one of the polarizing plates has a polarizer and a protective film with a Re of 5,000 nm or more and low moisture permeability. The device exhibits excellent color reproducibility and prevents display nonuniformity under a high temperature and high humidity environment.
