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.

摘要： A 2-dimensional beam scan unit reflects emission beams from a red laser light source, a green laser light source and a blue laser light source and scans in a 2-dimensional direction. Diffusion plates diffuse the respective light beams scanned in the 2-dimensional direction to introduce them to corresponding spatial light modulation elements. The respective spatial light modulation elements modulate the respective lights in accordance with video signals of the respective colors. A dichroic prism multiplexes the lights of the three colors after the modulation and introduces the multiplexed lights to a projection lens so that a color image is displayed on a screen. Since the 2-dimensional light emitted from the beam scan unit is diffused to illuminate the spatial light modulation element, it is possible to change the optical axis of the beam emerging from the light diffusion member for irradiating the spatial light modulation element moment by moment, thereby effectively suppressing speckle noise.
