  • Patent number: 9865834
    Abstract: A method of manufacturing a display device includes forming a three-layer laminate by laminating a first transparent conductive film, a metal film, and a second transparent conductive film in order from a substrate side. The three-layer laminate forms a plurality of anode electrodes arranged in a pixel region and a plurality of dummy electrodes arranged on an outer side of the pixel region. The method of manufacturing a display device also includes subjecting the second transparent conductive film and the metal film to etching and subjecting the first transparent conductive film to etching. A density of a pattern of the plurality of dummy electrodes is reduced as a distance from the pixel region is increased.
