Abstract
A display substrate, an Organic Light Emitting Diode (OLED) display device and a manufacturing method for the display substrate. The display substrate includes a plurality of pixel units located on a substrate and filter functional units corresponding to the pixel units. Each filter functional unit includes at least three micro-cavity structures, wherein the cavity lengths of the three micro-cavity structures in the direction of a vertical substrate are different, only light with a specific wavelength can penetrate through the micro-cavity structures with different cavity lengths, and the cavity lengths of micro-cavity structures corresponding to similar sub-pixel units of the pixel units are the same.
