Abstract

In a method of forming a matrix addressable display comprising a group of switchable cells, such as liquid crystal cells, having electrodes on each of two parallel plates and thin-film drive transistors disposed on one of the plates, gate resistors are provided by elongate doped polysilicon regions connecting the gate electrodes to address lines. The gate resistors prevent short-circuiting of the address lines in the event of a gate short-circuit occurring in any of the transistors.
