A display device comprising: a first display substrate including a light emitting element which emits light of a first color or light of a second color which is different from the first color; and a second display substrate facing the first display substrate, the second display substrate including in order toward the first display substrate: characterized by a first capping layer; a layer including both: a bank layer on the first capping layer defining an opening; and a wavelength control pattern (WCL, TPL) in the opening; a second capping layer covering the wavelength control pattern (WCL. TPL) and the bank layer; and a color absorbing layer which overlaps the bank layer and blocks the light of the first color and the light of the second color which is emitted from the light emitting element, wherein the second capping layer includes a first area overlapping the color absorbing layer, the bank layer includes a second area overlapping the color absorbing layer, the first capping layer includes a third area overlapping the color absorbing layer, the first area of the second capping layer is between the color absorbing layer and the second area of the bank layer and the first area of the second capping layer and the third area of the first capping layer are spaced apart from each other with the color absorbing layer interposed between. a first display substrate including a light emitting element which emits light of a first color or light of a second color which is different from the first color; and a second display substrate facing the first display substrate, the second display substrate including in order toward the first display substrate: characterized by a first capping layer; a layer including both: a bank layer on the first capping layer defining an opening; and a wavelength control pattern (WCL, TPL) in the opening; a second capping layer covering the wavelength control pattern (WCL.
