Abstract
A flat panel display device comprising a matrix of X and Y drive lines and a plurality of selecting field effect transistors (FETs) is described. Each FET is selectively operable by applying a potential across a unique pair of X and Y drive lines for controlling activation of a corresponding optical transducer. A high value resistance is interposed in series between the gate electrode of each selecting FET and associated drive line to minimize the effect a short circuit caused by a defective gate electrode establishing an electrical connection between X and Y drive lines. The resistance is preferably provided by a segment of undoped polysilicon on a polysilicon circuit line connecting each gate electrode with the associated X drive line.
