Abstract
The present application discloses a method for manufacturing a display substrate. The method comprises: coating all regions of a base substrate with an alignment film; performing a rubbing process on the base substrate coated with the alignment film; and removing the alignment film outside a display region of the base substrate by a photolithography process so as to retain only the alignment film in the display region. The present application further discloses a display substrate manufactured by such a manufacturing method, as well as a liquid crystal cell and a display comprising such a display substrate.
