An active matrix substrate includes a row and column array of active elements. Each element is associated with a TFT having a gate electrode connected to a corresponding row conductor and source and drain (electrodes connected to corresponding column conductors. Circuitry for protecting against electrostatic descharge (ESD) in connected to at least one of the row conductors for protecting the TFTs against ESD. A method for manufacturing the active matrix substrate includes forming semiconductor regions of the TFTs and the ESD protective circuitry, depositing gate electrodes of the TFTs and corresponding row conductors, and depositing source and drain electrodes of the TFTs and corresponding column conductors. The ESD protective circuitry operates to control ESD prior to deposition of the column conductors.
