Abstract

The disclosure provides a display substrate, a method for manufacturing the same and a display device, belonging to the display technology field, to solve the problem that ultraviolet irradiation has an adverse effect on the service life of existing OLED devices. The display substrate disclosed herein includes a light processing layer which comprising a condensed-ring conjugated polymer. The light processing layer can protect the display parts below it and prevent the display parts from being exposed to ambient light and reducing their service life.
