Liquid crystal display device
A liquid crystal display device (100) according to the present invention has a pixel (P), which includes red, green, blue and yellow subpixels (R, G, B and Y). The chromaticity of the yellow subpixel (Y) is outside of a triangle that is defined by connecting together the respective chromaticities of the red, green and blue subpixels (R, G and B). And the respective aperture areas SR, SG, SB and SY of the red, green, blue, and yellow subpixels (R, G, B and Y) and the respective transmittances TR, TG, TB and TY of their associated red, green, blue, and yellow color filters (CR, CG, CB and CY) satisfy the inequality TY>[(SR+SG+SB+SY)(TR+TG+TB)−3(SR×TR+SG×TG+SB×TB)]/3SY.
