摘要： In a liquid crystal display device including a liquid crystal display panel, and a backlight disposed on the rear surface of the liquid crystal display panel, the backlight is provided with a plurality of white light-emitting diodes arranged in a plane opposing the liquid crystal display panel. Based on a chromaticity coordinate value representing a color of emission identified for each of the white light-emitting diodes, the white light-emitting diodes are selectively combined for arrangement in proximity in such a manner that the color of emission as a result of averaging over the white light-emitting diodes (1a, 1b) to be arranged in proximity takes a predetermined value of chromaticity coordinates. Accordingly, the resulting liquid crystal display device can offer, although using the white light-emitting diodes having the problem of impairing the uniformity of the color of emission, higher-quality display images using a backlight with less non-uniformity of color and light emission as a whole, and prevents the increase of the manufacturing cost.

摘要： To suppress degradation of image quality caused by using an AC drive method so as to display a high-quality image. If a drive state of each of subpixels at a time when a gray-scale voltage higher than a counter voltage applied to a counter electrode is applied to a pixel electrode is defined as a positive drive state and if the drive state of each subpixel at a time when a gray-scale voltage lower than a counter voltage applied to the counter electrode is applied to the pixel electrode is defined as a negative drive state, an image line drive circuit changes the drive state of each subpixel from the positive drive state to the negative drive state or from the negative drive state to the positive drive state every two frames, as well as inverts a phase of the drive state of each subpixel every N (N≧4) frames. If a gray-scale voltage to be provided to each of image lines by an image line drive circuit in a frame A that is a first frame immediately after the phase inversion is defined as VA, and if a normal gray-scale voltage to be provided to each of the image lines by the image line drive circuit in a frame B that is a normal frame is defined as VB, |VA|
