PURPOSE: An apparatus for inspecting a substrate for LCD is provided to supply AC voltage to each signal line formed on a substrate by a non-contact method and to sense the signal line through a sensor unit. CONSTITUTION: A substrate transfer system transfers a substrate(2) in one direction. A feeding unit(210) supplies voltage to a signal line(12) on a transferred substrate by a non-contact method. A sensor unit(220) senses the signal line by using the non-contact method. A signal processing unit determines the short circuit and disconnection of the signal line through a voltage value measured through the sensor unit. |
