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

摘要

A display substrate includes a circuit mounted part that has a driving IC mounted thereon. The circuit mounted part includes an input pad part connected to an input terminal of the driving IC and an output pad part connected to an output terminal of the driving IC. A flexible pad part connected to a terminal of a FPCB includes a driving pad part to receive a drive signal of the driving IC. A driving line part is connected to the driving pad part to be extended along a length direction of the circuit mounted part within the circuit mounted part. Connection lines are extended from the driving line part disposed within the circuit mounted part toward the output pad part. The connection lines are partially removed in a trimming area defined between the driving line and the output pad part.

1. A display substrate, comprising:
at least one circuit mounted part comprising an input pad part coupled to an input terminal of a driving integrated circuit (IC) of the at least one circuit mounted part 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; an array pad part directly connected to the flexible pad part by at least one first inspection line part formed crossing a cutting line, the cutting line defining a display cell corresponding to the display substrate; a driving line part coupled to the driving pad part to be extended along a length direction of the at least one circuit mounted part; and a plurality of connection lines extended toward the output pad part from the driving line part and being disposed within the at least one circuit mounted part, wherein the at least one first inspection line part crosses the cutting line at least twice.
