摘要： A display device is provided. A display device including a plurality of light-output areas through which incident light is emitted and a light-blocking area which blocks the incident light, the display device includes a substrate, a bank layer which is disposed in the light-blocking area on the substrate and defines a plurality of openings, each of which is disposed in one of the plurality of light-output areas, and a color control pattern disposed in the opening of the bank layer, wherein the bank layer includes a first bank area which has a first thickness and defines the plurality of openings and a second bank area which is disposed between the plurality of openings and has a second thickness smaller than the first thickness.

摘要： 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.
