<p>PURPOSE:To improve the yield of liquid crystal display by eliminating the defect of an active matrix substrate by intervening capacitors between the gate electrodes of a plurality of membrane transistors and scan signal electrodes. CONSTITUTION:In the case where a short circuit occurs between the gate 14a of one Tr10a, for example, of membrane transistors Tr10 and a source 16a, the potential of a pixel electrode 19 does not become equal to the date potential due to the capacitor 18a intervened between a scan signal electrode 40 and gate 14a, but the writing of display data to the pixel electrode 19 is normally performed by the other transistor Tr10b. In addition, even if short circuit occurs between the gate 14b of the transistor Tr10b and a drain 16b, display can be made without the line defect caused by the mutual pulling of both bus lines of the gate and drain because of the intervention of a capacitor 18b. The capacitance of capacitors 18a and 18b is desirable to be 10 times as much as the gate capacitance of Tr10a and 10b.</p> |
