Abstract

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.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] At present, smart devices generally adopt touch technology to realize human-computer interaction. Touch panels (touch panels) can be classified into add-on touch panels, on-cell touch panels and in-cell touch panels according to their composition and structure. The plug-in touch screen is produced separately from the touch screen and the LCD panel, and then bonded to the LCD panel to have a touch function. The production cost of the plug-in touch screen is high, the light transmittance is low, and the module is thick. In the surface-covered touch screen, the touch electrodes are arranged between the color filter substrate and the polarizer of the liquid crystal panel. In the embedded touch screen, the touch electrodes are arranged inside the liquid crystal pane...
