The invention discloses a display base plate and a manufacturing method of the display base plate as well as a display device. The display base plate comprises a substrate base plate, a patterned black matrix and a touch electrode, wherein the patterned black matrix is arranged on the substrate base plate; in the region of the black matrix, the display base plate comprises a light filtering layer laminating layer located on the black matrix; the light filtering layer laminating layer comprises more than two colored light filtering layers which are stacked in sequence, and is provided with a plurality of openings; the touch electrode is arranged on the light filtering layer laminating layer and covers the surface provided with the plurality of openings. According to the display base plate disclosed by the invention, the light filtering layer laminating layer provided with the plurality of openings is arranged in the region of the black matrix of the display base plate, so that the surface area of the touch electrode, covered by the light filtering layer laminating layer, is enlarged, and more charges can be easily gathered, and furthermore, the touch sensitivity and the touch accuracy are improved.
