Abstract
The present disclosure discloses a display substrate and a display panel, a method for manufacturing the same and a display device. The method for manufacturing the display substrate includes a step of form an optical grating. The step of forming the optical grating includes: forming an intermediate layer on an outer surface of a transparent base substrate in such a manner that the intermediate layer includes stripe patterns arranged at intervals; forming a display film layer on an inner surface of the transparent base substrate where the intermediate layer is formed; and applying an opaque material onto a surface of the intermediate layer or between the stripe patterns of the intermediate layer on the transparent base substrate, to form light-shielding stripes and light-transmitting stripes which are arranged alternately.
