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 theA sub-region is larger than that of theA sub-region, the in-plane birefringence of theA sub-region is smaller than that of theA sub-region, and an in-plane birefringence of theB sub-region is the same as that of theB sub-region, smaller than that of theA sub-region and larger than that of theA sub-region.

Retardation substrate, semi-transparent liquid crystal display, and method for manufacturing retardation substrate

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&#x2266;&#x394;n[fr]/&#x3bb;d[fr]&#x2266;1.35 for a region corresponding to a reflection part of a pixel and satisfying &#x394;n[t]&#x3c;1.2 &#xd7;10for a region corresponding to a transmission part of a pixel.

Liquid crystal display device and method for manufacturing the same

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.

Film checking apparatus

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. A correction/conversion method and an apparatus therefor are also provided which have a function of mixed-color correction and a function of converting the signals (Y), (M), (C) and (K) into signals (B), (G) and (R) for the color monitor.
