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

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

• forming a gate line, a first sensor line parallel with the gate line and a first sensor gate electrode extended from the first sensor line;
• forming a sensor active pattern having a plurality of island-type sub-active members on a base substrate on which the first sensor gate electrode is formed;
• forming a second sensor line, a first sensor drain electrode and a second sensor drain electrode, the second sensor line being parallel with the data line, the first sensor drain electrode being formed on the sensor active pattern and being extended from the second sensor line, the second sensor drain electrode being formed on the sensor active pattern and corresponding to the first sensor gate electrode;
• and
• forming a pixel electrode and a sensor electrode part, the pixel electrode being electrically connected to the gate line and the data line, the sensor electrode part electrically connecting the first and second sensor drain electrodes with each other.

A display panel comprising:

• a display substrate comprising:
• a base substrate on which a gate line and a data line are formed;
• a first sensor line parallel with the gate line;
• a first sensor gate electrode extended from the first sensor line;
• a sensor active pattern having a plurality of island-type sub-active members, and formed on the first sensor gate electrode;
• a second sensor line parallel with the data line;
• a first sensor drain electrode formed on the sensor active pattern and extended from the second sensor line;
• a second sensor drain electrode formed on the sensor active pattern and corresponding to the first sensor gate electrode;
• a pixel electrode electrically connected to the gate line and the data line;
• and
• a sensor electrode part spaced apart from the pixel electrode, and electrically connecting the first and second sensor drain electrodes with each other,
• a counter substrate facing the display substrate;
• and
• a liquid crystal layer disposed between the display substrate and the counter substrate.
