Display substrate and a method of manufacturing the same

A display substrate, comprising:

• a transistor layer including a transistor connected to a gate line and a data line crossing the gate line, wherein the transistor is disposed in a display area of a base substrate;
• a plurality of color filters disposed on the transistor layer and formed in a pixel area of the base substrate;
• a first blocking member disposed between different color filters, wherein the first blocking member blocks light;
• a supporting member maintaining a distance between the base substrate and a substrate facing the base substrate, wherein the supporting member includes a blocking member comprising substantially the same material as the first blocking member;
• a circuit part disposed in a peripheral area surrounding the display area, wherein the circuit part includes a metal pattern and a contact electrode in contact with the metal pattern;
• a second blocking member comprising substantially the same material as the first blocking member, wherein the second blocking member covers the circuit part;
• and
• a protruding member comprising substantially the same material as the second blocking member, wherein the protruding member is integrally formed with the second blocking member.
