Claim Text:
1. An image display unit, comprising: an image display section having pixels arranged two-dimensionally in a matrix pattern, the pixels each including a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel; and a signal generating section configured to generate a red sub-pixel signal, a green sub-pixel signal, a blue sub-pixel signal, and a white sub-pixel signal, based on a red-display image signal, a green-display image signal, and a blue-display image signal that are provided in accordance with an image to be displayed, the signal generating section being configured to determine values of the red sub-pixel signal R the coefficient ‘Purity’ being defined by a value obtained through subtracting the min (R the additive-color-mixture matrix being defined in accordance with specification of the image to be displayed, a product of the additive-color-mixture matrix and a three-rows-one-column matrix composed of the signals (R the purity coefficient ‘Ψ’ having a value that varies to approach a value ‘TH the first matrix being configured of a difference obtained through subtracting first tristimulus values from second tristimulus values, the first tristimulus values being a product of the additive-color-mixture matrix and the matrix of the signals (R the second matrix being an inverse matrix of a matrix obtained through multiplying the additive-color-mixture matrix by ‘TH
