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 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 switching elements for selectively electrically connecting at least one of said pixel electrodes to a corresponding one of said source buses in the event said at least one pixel electrode is considered to be defective.

Active matrix display device

An active matrix display device which includes a first and a second insulating substrates, a gate bus an adjacent gate bus, and a source bus arranged on the first substrate, a pixel electrode in a segment enclosed by the gate and the source buses, a switching element connected to the pixel electrode, the gate bus and the source bus, wherein the source bus comprises a projection extending toward the pixel electrode so as to be electrically disconnected therefrom, and the adjacent gate bus comprises a projection extending toward the pixel electrode, the source bus being overlaid on the adjacent gate bus projection with an insulating layer sandwiched therebetween, the adjacent gate bus projection being provided with an electroconductive member at the top thereof with an insulating layer sandwiched therebetween, the electroconductive member being electrically connected to the pixel electrode, and electrically disconnected from the source bus projection.
