Abstract:
A liquid crystal display comprising:a backlight source having a dominant emission peak at 460 to 470 nm; a first polarization layer in vertical alignment with said backlight source and for selecting a light directed in a predetermined direction among light emitted from said backlight source; a second polarization layer in vertical alignment with said first polarization layer and for receiving a light selected from said first polarization layer; first and second light-permeable substrates located on opposite sides of said second polarization layer; first and second light-permeable electrodes located on opposite sides of a liquid crystal layer; and a fluorescent material layer in vertical alignment with and receiving lights from said backlight source and emitting a light therefrom, wherein said fluorescent material layer includes a first fluorescent material emitting red lights in response to lights emitted from said backlight source, a second fluorescent material emitting green lights in response to lights emitted from said backlight source, transparent film passing therethrough lights emitted from said backlight source, said first and second fluorescent materials and said transparent film being arranged in a line, and light-impermeable layers located between said first and second fluorescent materials and said transparent film.
