A liquid crystal display device, which is configured to have a liquid crystal layer held between a pair of substrates, includes a display area including a red color pixel, a green color pixel and a blue color pixel, a pixel electrode which is disposed in each of the color pixels, a counter-electrode which is opposed to the pixel electrode via an interlayer insulation film, and an alignment film which is disposed in contact with the liquid crystal layer and is subjected to such rubbing treatment as to restrict alignment of liquid crystal molecules included in the liquid crystal layer. The pixel electrode has a slit which is formed to be inclined with respect to a direction of rubbing of the alignment film, and the slit of the red pixel and the slit of the blue pixel are formed to be inclined in different directions.

An image forming apparatus is provided that forms an image using developers of different tone and the same hue. When forming images for measurement for density control, the apparatus performs density control by forming a greater number of density levels of an image for measurement developed using a light developer than the number of density levels of an image for measurement developed using a dark developer. Thus, even if the amount of applied light developer may fluctuate, the fluctuation can be compensated to prevent the occurrence of pseudo-contours that lower image quality.

A liquid crystal display device according to the present invention includes a liquid crystal panel which has a liquid crystal cell including a predetermined liquid crystal layer and polarizing plates for holding the liquid crystal cell, a backlight source which is arranged on the rear side of the liquid crystal panel, for irradiating the liquid crystal panel with white light, and an absorbing layer which is arranged between the backlight source and the liquid crystal cell, for absorbing only the light of the wavelength band corresponding to a changed color of the white light while passing through the liquid crystal panel in the oblique direction with respect to the normal direction of the liquid crystal panel.

The retardation film for VA contains a cellulose ester resin, and satisfies the following conditions (1) and (2) at the same time. Condition (1): Smd+Std≤0.65%, where Smd and Std respectively represent the length direction and Dimensional change rate (%) in film width direction. Condition (2): Rth2‑Rth1≤9nm, where Rth1 refers to the retardation (nm) measured in the thickness direction when the film is sandwiched between two transparent substrates without using an adhesive, and Rth2 refers to the retardation (nm) measured with two transparent substrates. Retardation (nm) in the thickness direction measured when the substrate sandwiches the film and an adhesive is present between the film and a transparent substrate.

Disclosed is an ink-jet recording method. In the method, the recording is carried out on an ink-jet recording medium which comprises a support and an ink-receiving layer arranged over the support as the outermost layer and comprising at least a water-soluble resin, a cross-linking agent and inorganic microparticles having a secondary particle diameter of 45 nm or smaller as measured on an electron microscope. In the method, the recording is carried out by using an ink which comprises at least a dye, water and a water-soluble organic solvent component. In the ink, the water-soluble organic solvent component contains a water-soluble organic solvent at a ratio of 40 mass% or more relative to the total quantity of the water-soluble organic solvent component. The water-soluble organic solvent has such a property that, when applied on the outermost layer at a rate of 6.6 g / m2, the rate of change in secondary particle diameter of the inorganic microparticles in the outermost layer before and after the application on the outermost layers is 100% or less.

An ink containing a first coloring material and a second coloring material, the sum total of these contents being 6.0% by mass or less. The first coloring material is a black coloring material exhibiting a difference ”» max1 of 20.0 or more between a maximum absorption wavelength in a 20.0% by mass aqueous solution of 1,2-hexanediol and a maximum absorption wavelength in water, the second coloring material is a specific coloring material exhibiting a difference ”» max2 of 12.0 or less between a maximum absorption wavelength in a 20.0% by mass aqueous solution of 1,2-hexanediol and a maximum absorption wavelength in water, and the sum of the ”» max1 and the ”» max2 is 35.0 or less.

A production method of an optical film, including: a stretching step of stretching a film, wherein the film has a longitudinal direction, a width direction and a thickness direction, wherein the stretching is in either of the longitudinal direction or the width direction of the film; and a shrinking step of shrinking the film in either of the longitudinal direction or the width direction of the film, that is not the direction in which the film is stretched, wherein the film thickness in the thickness direction is increased as compared with the film thickness before at least one of the stretching step and the shrinking step.

The present invention provides an N-vinyl lactam polymer that is less likely to be colored (yellowing) even at high temperatures to maintain its color tone. The present invention provides an N-vinyl lactam polymer comprising a structural unit derived from an N-vinyl lactam monomer, the N-vinyl lactam polymer including a structural unit that has at least one of a hypophosphorous group and a group of hypophosphorous acid metal salt at a main chain terminal.
