Abstract: Embodiments of the present invention disclose a display substrate and a method of manufacturing the same, and a display device comprising the display substrate. The display substrate comprises: a substrate; a black matrix layer and a color filter layer located on the substrate; and at least one main spacer and at least one secondary spacer located on the black matrix layer or the color filter layer and both having direct projections on the substrate within a region where the black matrix layer is located. A sum of thicknesses of portions of the black matrix layer and the color filter layer corresponding to each secondary spacer is smaller than that of portions of the black matrix layer and the color filter layer corresponding to each main spacer, so that a distance from a top end of the secondary spacer to the substrate is smaller than a distance from a top end of the main spacer to the substrate.

Abstract: The present disclosure provides an OLED display device, a method for manufacturing the same, and an OLED display apparatus. The OLED device includes: a base substrate, an anode layer, a hole injection layer, a hole transport layer, a light emitting material layer, an electron transport layer, an electron injection layer, a cathode layer and a packaging layer, wherein the hole injection layer, the hole transport layer, the electron transport layer and/or the electron injection layer are doped with a water-absorbing organic compound and an oxygen-absorbing organic compound.

Abstract: A color filter and a fabricating method thereof, and a display apparatus are provided. The color filter includes: at least four pixel units, and each pixel unit includes a color filter layer, and the four pixel units are a first pixel unit, a second pixel unit, a third pixel unit and a fourth pixel unit, respectively. A first color filter layer is formed in the first pixel unit, a second color filter layer is formed in the second pixel unit, a third color filter layer is formed in the third pixel unit, a fourth color filter layer is formed in the fourth pixel unit, and the fourth color filter layer is formed by stacking any two materials of the first, second and third color filter layers.
