Abstract

PURPOSE:To obtain an easy to see and beautiful display having no dependency on visual angles by oxidizing thin films of transition metals to the transparent or white films of a desired pattern shape, using these oxidized parts as display parts, and forming the opaque parts of the transition metals as nondisplay parts within the same layers as those for the display parts. CONSTITUTION:A transparent electrode 2 and electrolytic reduction coloring thin films 3a, 3b consisting of WO3 are laminated on a transparent substrate 1 of glass, etc. Next, an insulation characteristic thin film 4 of proton good conductor of Ta2O5, etc., a thin film 5 of Ir metal thereon, and a transparent electrode 6 of In2O3, etc., are laminated successively. The film 5 is of a dark grayish color and is nearly opaque, but when 1.0-1.6V alternating electric fields are applied between the electrodes 2 and 6, the Ir metal is anodized by the moisture in the film 4 or the atmospheric air to Ir(OH)3 so that only the parts A of the film 5 opposite to the WO3 films 3a, 3b turn transparent during decoloring and color to the density about the same as that of the uncolored parts B of the films 5 during coloring. Since the Ir(OH)3 has electrolytic oxidation colorability, this in combination with the WO3 films 3a, 3b provide the transparent negative display.
