摘要： A liquid crystal display device comprises a liquid crystal layer sandwiched between upper and lower electrode substrates subjected to aligning treatment. The liquid crystal layer includes a nematic liquid crystal added with a chiral material and has a 160.degree.-360.degree. twisted helical structure. A pair of polarizers are disposed adjacent to the electrode substrates with their polarization or absorption axes inclined by respective predetermined angles with respect to the aligning directions of the electrode substrates. At least one of the polarizers is formed by a color polarizer for compensating a wavelength dependence of transmittance (or the coloring due to birefringence) resulting from the anti-coincidence between the polarization or absorption axis of the polarizer and the aligning direction of the electrode substrate, i.e. an optical axis of liquid crystal molecules adjacent to the substrate, so that light emerging from the device becomes approximately achromatic or colorless.

摘要： An image forming apparatus includes an obtaining unit, an image forming section, and a controller. The obtaining unit obtains color signals containing color components the number of which is n, n being a natural number. The image forming section forms an image on a medium, the image being based on the color signals obtained by the obtaining unit. The controller performs control so that colors in a color gamut that is not reproduced if area coverage modulation, not density modulation, is used for expression are included in the image by expressing densities of the n color components contained in the color signals obtained by the obtaining unit by using density modulation and area coverage modulation.
