A liquid crystal display device (100A) of the present invention includes an active matrix substrate (220); a counter substrate (240); and a vertical alignment type liquid crystal layer (260). The liquid crystal display device (100) has a plurality of pixels, each of the pixels including a plurality of subpixels. The plurality of subpixels include a red subpixel (R), a green subpixel (G), and a blue subpixel (B). When each of adjacent two of the plurality of pixels represents an achromatic color at a certain grayscale level, a luminance of a blue subpixel (B) included in one of the two adjacent pixels is different from a luminance of a blue subpixel (B) included in the other of the two adjacent pixels.

摘要:
A signal conversion circuit (20) is used for a multiple-primary color liquid crystal display device (100) which performs color display using four primary colors of red displayed by a red-sub pixel (R), green displayed by green-sub pixel (G), blue displayed by blue-sub pixel (B), and yellow displayed by yellow-sub pixel (Ye), and converts an input three-primary color video signal into a multiple-primary color video signal corresponding to four primary colors. The signal conversion circuit (20) performs signal conversion such that a gray scale level of the yellow-sub pixel (Ye) is higher than a gray scale level of the green-sub pixel (G) in at least some cases from among cases in which a red gray-scale level r, a green gray-scale level g, and a blue gray-scale level b which are displayed by the three-primary color video signal satisfy a relationship of r>g>b.
