Multiple primary color liquid crystal display device and signal conversion circuit
The viewing angle characteristics of a multiprimary liquid crystal display device in which a plurality of red subpixels are provided in each pixel are improved.A multiprimary liquid crystal display device according to the present invention includes a pixel defined by a plurality of subpixels, and performs multicolor display by using four or more primary colors to be displayed by the plurality of subpixels. The plurality of subpixels of the multiprimary liquid crystal display device according to the present invention include first and second red subpixels R1 and R2 for displaying red, a green subpixel G for displaying green, a blue subpixel B for displaying blue, and a cyan subpixel C for displaying cyan. When a color having a hue which is within a predetermined first range is displayed by the pixel, the gray scale level of the first red subpixel R1 and the gray scale level of the second red subpixel R2 differ from each other. When a color having a hue which is within a second range different from the first range is displayed by the pixel, the gray scale level of the first red subpixel R1 and the gray scale level of the second red subpixel R2 are equal.
