  • Publication number: 20240142847
    Abstract: A display device includes a panel, a conductive layer, a first color filter array and a second color filter array. The panel has a display surface and multiple sub-pixel regions where the multiple sub-pixel regions and the conductive layer are on this display surface. The first color filter array including multiple first color filter elements is disposed on the conductive layer while the second color filter array including multiple second color filter elements is disposed on the first color filter array. One first overlaid region and one second overlaid region are defined by the orthogonal projections of the color filter elements within one of the sub-pixel regions. In one sub-pixel region, a section of the first overlaid region does not overlap a section of the second overlaid region.
