Method of manufacturing a display substrate

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

• forming a common electrode line, a gate line, a data line and a switching element connected to the gate and data lines on an insulation substrate;
• sequentially forming a first pixel electrode and an insulation layer on the insulation substrate on which the switching element is formed;
• forming a first photoresist pattern from a first photoresist layer on the insulation substrate on which the insulation layer is formed, the first photoresist pattern including a first hole and a second hole formed through the first photoresist pattern, the first contact hole exposing the common electrode line, the second hole exposing the first pixel electrode;
• coating a first transparent electrode layer on the insulation substrate on which the first photoresist pattern is formed;
• coating a second photoresist layer on the insulation substrate on which the first transparent electrode layer is formed;
• exposing and developing the second photoresist layer to form a second photoresist pattern remaining in the first hole and the second hole;
• and
• patterning the first transparent electrode layer using the second photoresist pattern, to form a second pixel electrode making contact with the common electrode line and including a plurality of openings formed through the second pixel electrode.
