Abstract
A color display improves the contrast of a shown image without decreasing an open area ratio. A color electroluminescent display of the present invention has electroluminescent elements provided on a black insulation layer. A predetermined space exists between each adjacent pair of the electroluminescent elements. Filter elements are provided on the electroluminescent elements. The interface between each adjacent pair of the filter elements extends along the thickness direction of the color electroluminescent display and is aligned with one of the spaces.
