Abstract:
1. A liquid crystal display comprising: a light source section; a liquid crystal display panel including a plurality of pixels each configured of sub-pixels of three colors red (R), green (G) and blue (B) and a sub-pixel of a color (Z) with higher luminance than the three colors, and modulating, based on input picture signals corresponding to the three colors R, G and B, emission light from the light source section to display a picture; and a display control section including an output signal generation section which performs a predetermined conversion process based on the input picture signals to generate output picture signals corresponding to four colors R, G, B and Z, and performing a display drive on each of the sub-pixels of R, G, B and Z in the liquid crystal display panel with use of the output picture signals, wherein a chromaticity point of the emission light from the light source section is set to a position deviated from a white chromaticity point, and in the case where the input picture signals are picture signals indicating white (W), the output signal generation section performs a chromaticity point adjustment in the conversion process to adjust, to the white chromaticity point, a chromaticity point of display light emitted from the liquid crystal display panel based on the emission light from the light source section.
