<p>PROBLEM TO BE SOLVED: To make it possible to repair the defect of switching elements having a multigate structure. SOLUTION: This active matrix display device has a panel structure consisting of a pair of driving substrates and a counter substrate joined to each other via spacings and liquid crystals held in these spacings. Gate lines 1 and signal lines 2 intersected with each other, the switching elements 3 disposed in the intersected parts of both and pixel electrodes 4 driven by these switching elements 3 are formed on the driving substrates. Counter electrodes facing the pixel electrodes 4 are formed on the counter substrate. Each switching element 3 consists of two pieces of thin-film transistors(TFTs) 3a, 3b connected in series between the signal lines 2 and the pixel electrodes 4. The junctures 8a of the adjacent TFTs 3a, 3b are provided with repair regions 7 for repairing the defect which electrical short the pixel electrodes 4 corresponding to these junctures. Even if the one TFT 3b goes out of order, the driving of the pixel electrode 4 by using only the other TFT 3a is made possible by such constitution.</p> |
