Display substrate, method for manufacturing the same and display apparatus having the same

A method for manufacturing a display substrate, the method comprising:

• forming a signal line and a thin-film transistor electrically connected to the signal line on a base substrate;
• forming a light-blocking part on the base substrate, the light-blocking part including an organic pattern and a light-blocking pattern;
• forming a color filter in a unit pixel area of the base substrate in which the light-blocking part is not formed;
• and
• forming a pixel electrode, electrically connected to the thin-film transistor, on the color filter, wherein
• the organic pattern is formed along a longitudinal axis of the signal line and defines at least a portion of a periphery of the color filter,
• the organic pattern covers the thin-film transistor,
• the light-blocking pattern is formed on the organic pattern, and
• a size and a shape of the light-blocking pattern are substantially the same as a size and a shape of the organic pattern.

A display apparatus comprising:

• a first substrate;
• a second substrate facing the first substrate;
• and
• a liquid crystal layer disposed between the first substrate and the second substrate, wherein the first substrate comprises:
• a base substrate;
• a signal line formed on the base substrate;
• a thin-film transistor formed on the base substrate and electrically connected to the signal line;
• a pixel electrode formed in a unit pixel area of the base substrate and electrically connected to the thin-film transistor;
• a color filter formed in the unit pixel area;
• and
• a light-blocking part including an organic pattern formed on the base substrate and a light-blocking pattern formed on the organic pattern, wherein
• the organic pattern is formed along a longitudinal axis of the signal line to define at least a portion of a periphery of the color filter,
• the organic pattern covers the thin-film transistor, and
• a size and a shape of the light-blocking pattern are substantially the same as a size and a shape of the organic pattern.
