  • Patent number: 12193279
    Abstract: A display device includes a first display substrate including a light emitting element which emits light of a first color or light of a second color different from the first color, a second display substrate including in order toward the first display substrate, a layer including both a bank layer defining an opening and a wavelength control pattern in the opening, a capping layer covering the wavelength control pattern and the bank layer, and a color absorbing layer which corresponds to the bank layer and blocks the light of the first color and the light of the second color. The capping layer includes a first area corresponding to the color absorbing layer, the bank layer includes a second area corresponding to the color absorbing layer, and the first area of the capping layer is between the color absorbing layer and the second area of the bank layer.
