Display substrate, mother substrate for manufacturing the same and method of manufacturing the display substrate

A mother substrate comprising:

• a cutting line;
• and
• a display cell defined by the cutting line, the display cell comprising:
• a circuit mounted part comprising a driving integrated circuit (“IC”) and an input pad part coupled to an input terminal of the driving IC and an output pad part coupled to an output terminal of the driving IC;
• a flexible pad part coupled to a terminal of a flexible printed circuit board, the flexible pad part comprising a driving pad part to receive a drive signal of the driving IC;
• a driving line part coupled to the driving pad part to be extended along a length direction of the circuit mounted part;
• and
• a plurality of connection lines extended from the driving line part disposed within the circuit mounted part toward the output pad part, the connection lines partially being removed in a trimming area defined between the driving line and the output pad part.

A method comprising:

• disposing a display cell being defined by a cutting line;
• mounting a circuit mounted part comprising a driving integrated circuit (“IC”) and an input pad part coupled to an input terminal of the driving IC and an output pad part coupled to an output terminal of the driving IC;
• disposing a flexible pad part coupled to a terminal of a flexible printed circuit board, the flexible pad part comprising a driving pad part to receive a drive signal of the driving IC;
• and
• disposing a driving line part coupled to the driving pad part to be extended along a length direction of the circuit mounted part, wherein
• a plurality of connection lines are extended from the driving line part disposed within the circuit mounted part toward the output pad part, the connection lines partially being removed in a trimming area which is defined between the driving line and the output pad part.
