Abstract: A retardation substrate is provided, which includes a substrate and an optically anisotropic solidified liquid crystal layer which is supported by the substrate and formed as a continuous film made from a same material. The solidified liquid crystal layer comprises first to third regions each having two sub-regions which are a sub-region A and a sub-region B, an in-plane birefringence of the 1A sub-region is larger than that of the 2A sub-region, the in-plane birefringence of the 3A sub-region is smaller than that of the 2A sub-region, and an in-plane birefringence of the 1B sub-region is the same as that of the 3B sub-region, smaller than that of the 1A sub-region and larger than that of the 3A sub-region.

Abstract: A liquid crystal display device may include a first substrate; a second substrate; a first polarizing plate on the first substrate; a second polarizing plate arranged on the second substrate, and so that a direction of an absorption axis of the second polarizing plate being perpendicular to a direction of an absorption axis of the first polarizing plate; a liquid crystal layer arranged between the first substrate and the second substrate; a color filter layer arranged between the liquid crystal layer and the first or the second substrate, the color filter layer having a plurality of pixels of two or more colors. The retardation thin film has in-plane birefringence index satisfying 0.75??n[fr]/?d[fr]?1.35 for a region corresponding to a reflection part of a pixel and satisfying ?n[t]<1.2 ×10?3 for a region corresponding to a transmission part of a pixel.

Abstract: A film checking apparatus which picks up images of two master films placed on two transparent film tables, displays the obtained images thereof on a color monitor thereby allowing for checking of the master films. The apparatus aids the film checking by providing a device for comparing the master films, detecting for the differences and finally displaying the differences in a blinking manner. The apparatus also provides two light sources and a means to switching between the two light sources depending on whether the object is of transmissive-type or reflective-type.

Abstract: A method and an apparatus for correcting video signals are provided for printing simulation with a color monitor. Excellent mixed-color simulation can be performed in a printing process processing with a relatively high U.C.R.%. Mixed-color signals of secondary colors, a tertiary color, a quaternary color, black x primary colors, and black x secondary colors are detected from the signals (Y), (M), (C) and (K) for yellow Y, magenta M, cyan C and black K. The mixed-color signals are subjected to overlap compensation to provide overlap-compensated mixed-color signals. The signals (Y), (M), (C) and (K) are corrected using the overlap-compensated mixed-color signals so as to reduce color value of the mixed-colors in small portions. Printing simulation with a color monitor is facilitated.
