Abstract
A color image is displayed by using a display panel with a color pattern layer which is formed on one side of a transparent substrate and has, for example, three separate sets of transparent pixel areas in red, green and blue colors which constitute a regularly repetitive pattern and a set of opaque band-like areas by which each pixel area is bordered. The display panel further comprises, usually on the opposite side of the substrate, either a thermal recording layer which exhibits reversible changes in transmittance with temperature or a magnetic recording layer which contains flaky particles of a ferromagnetic metal dispersed in a polymer and exhibits reversible changes in transmittance with orientations of the flaky particles. To display an image, the thermal recording layer is heated in areas opposite to selected pixel areas of the color pattern layer, or a magnetic field parallel to or perpendicular to the display panel is applied to the magnetic recording layer in areas opposite to selected pixel areas, and then the display panel is backlighted.
