Abstract
An image display device for special uses which improves a color resolution of a particular color and increases a color reproducibility is provided. In the image display device, an area in which a gradient is gentle is provided to a partial region of a gamma curve denoted by a relationship of an input value (gray level) and an output value (luminance relative value) so that chromaticity points on chromaticity coordinates are unevenly distributed, thereby improving a chromatic resolving power (color resolution) of a particular color. In this manner, the color reproducibility of special monitors which display images of a particular color range represented by a monitor for remote metical care and a monitor for surgical operation can be improved.
