A display substrate includes gate lines and source lines, a passivation layer, a light shielding layer, an overcoat layer, and a column spacer. The passivation layer includes a first hole, partially exposing the metal layer. The passivation layer is formed on the substrate having the metal layer formed thereon. The light shielding layer overlaps the metal pattern and includes a positive photosensitive material on the passivation layer. The light shielding layer includes a second hole corresponding to the first hole. The overcoat layer includes a positive photosensitive material on the substrate having the light shielding layer thereon. The overcoat layer includes a third hole corresponding to the second hole. The column spacer is protruded from the overcoat layer corresponding to a portion of the light shielding layer. Accordingly, the number of the exposing mask used for manufacturing the display substrate may be reduced.
