Claim:
1. An image display apparatus, comprising: an image display unit in which pixels constituted by a red color sub-pixel, a green color sub-pixel, a blue color sub-pixel, and a white color sub-pixel are arranged in a two-dimensional matrix manner; and a signal generation unit configured to generate a signal for the red color sub-pixel, a signal for the green color sub-pixel, a signal for the blue color sub-pixel, and a signal for the white color sub-pixel on the basis of an image signal for red color display, an image signal for green color display, and an image signal for blue color display which are provided according to an image to be displayed, wherein the image signal for red color display, the image signal for green color display, and the image signal for blue color display which are linearized and normalized and which correspond to a pixel are denoted as reference symbol R in a case, where MinRGB the value of the signal for the white color sub-pixel is MinRGB the value of the signal for the red color sub-pixel is R the value of the signal for the green color sub-pixel is G the value of the signal for the blue color sub-pixel is B in a case, where MinRGB the value of the signal for the white color sub-pixel is 1, the value of the signal for the red color sub-pixel is (R the value of the signal for the green color sub-pixel is (G the value of the signal for the blue color sub-pixel is (B
