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： Disclosed is a liquid crystal display device, which is capable of reducing a required response speed and increasing a pixel aperture ratio, as compared with a field sequential driving scheme. A unit pixel of a liquid crystal display panel is made up of a first sub-pixel adapted to allow only any two of red, green and blue lights to pass therethrough, and a second sub-pixel adapted to allow only a remaining one of the red, green and blue lights to pass therethrough, wherein one frame of image is time-divided into n pieces (wherein n is an integer of two or more), and respective image information about the two lights are applied to the first sub-pixel during every duration of the 1/n frame, while applying image information about the remaining one light to the second sub-pixel during a duration of the one frame of image. Further, the respective two lights are emitted during every duration of the 1/n frame in synchronization with applying the respective image information about the two lights, while continuously emitting the remaining one light during the duration of the one frame of image.

A light-guiding plate includes a light-guiding section in which a plurality of right prisms of the same shape for extracting the laser light by contacting the optical fiber are arranged parallel to each other in the same direction at equal intervals. A planar section diffuses the laser light extracted from the light-guiding section and emits the diffused laser light from one main surface. The optical fiber is bent more than twice to form a plurality of straight line portions arranged parallel to each other at unequal intervals, and the optical fiber and the light-guiding plate are positioned such that the laser light is extracted at equal intervals from each of the plurality of straight line portions.
