摘要： Disclosed is a liquid crystal display device capable of performing image display with more adequate white level, during an operation of displaying an image which requires emphasizing white. A backlight illuminator for illuminating a liquid crystal display panel comprises a white light source adapted to generate white light, in addition to a laser source adapted to generate red light, blue light and green light. When an image to be displayed on a liquid crystal display panel requires emphasizing white, white light from the white light source is emitted to a liquid crystal display panel, in addition to red light, blue light and green light from the laser source. This makes it possible to display the image which requires emphasizing white, in the form of an image with more natural image quality.
