Display device with electrostatic discharge protection circuitry

An electronic device comprising:

• an array of pixels provided on a substrate and arranged in rows and columns, each pixel comprising a switch element;
• and
• a plurality of row and column address lines for addressing each pixel,
• wherein:
• each row and column address line is connected to a first discharge element through a first discharge device and to a second discharge element through a second discharge device,
• the first discharge device provides a unidirectional current path that allows the passage of charge between the address line and the first discharge element when the address line is at a potential below that of the first discharge element, and the second discharge device provides a unidirectional current path that allows the passage of charge between the address line and the second discharge element when the address line is at a potential above that of the second discharge element,
• the first and second discharge elements are initially short-circuited, and the connection between the first and second discharge elements is broken down before the operation of the electronic device, and
• at least one of the first and second discharge elements has a configuration in which the one is in a substantially electrically floating state during ordinary operation of the electronic device.
