Patent ID: 8077275

Claim:
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.
