Active matrix display device

An active display device, comprising:

• a plurality of source buses and a plurality of gate buses;
• a plurality of pixel electrodes, said pixel electrodes each having associated therewith a single switching element for delivering a drive signal to said pixel electrode from at least one of said source buses as a function of a signal provided by at least one of said gate buses;
• and
• means other than said single switching element for selectively and permanently electrically connecting at least one of said pixel electrodes to a corresponding one of said source buses and a projection of a corresponding one of said gate buses when said at least one pixel electrode is defective;
• said connecting means including a source bus projection extending from said corresponding source bus and said gate bus projection extending from said corresponding gate bus, said source bus projection and gate bus projection overlapping each other with an insulating layer positioned therebetween, and said gate bus projection also overlapping said at least one pixel electrode with said insulating layer positioned therebetween.

An active display device, comprising:

• a pixel electrode;
• a single switching element associated with said pixel electrode for providing a drive signal from a source bus to said pixel electrode as a function of a signal on a gate bus;
• and
• means for electrically connecting said pixel electrode to said source bus via a projection from said gate bus with fused connections when said pixel electrode is defective, said connecting means maintaining a permanent electrical connection;
• wherein said connecting means includes a source bus projection extending from said source bus and said gate bus projection extending from said gate bus, said source bus projection and gate bus projection overlapping each other with an insulating layer positioned therebetween, and said gate bus projection also overlapping said pixel electrode with said insulating layer positioned therebetween.
