ABSTRACT:
An object of the invention is to provide electrostatic discharge damage protection during manufacturing and to suppress power consumption as low as possible during ordinary use of the electronic device having been manufactured, with avoidance of the problem of electric corrosion. An electronic device10comprising an array of pixels12wherein row and column address lines18, 20for addressing each pixel12are arranged. Each address line is connected to a discharge line30, 32through a discharge38. The circuit allows the passage of charge between the address line and the first discharge line30when the address line is at a potential below that of the first discharge line, and allows the passage of charge between the address line and the second discharge line32when the address line is at a potential above that of the second discharge line. The discharge elements have a configuration in which the one is in an electrically floating state during ordinary operation of the electronic device, or a conductive path making conduction in order that leakage current of the discharge device occurring during ordinary operation of the electronic device can be used for the peripheral circuitry.
