Abstract
A driving circuit of at least one embodiment includes: m output terminals; m+1 video signal output sections including m+1 output circuits, respectively; a decision section for determining the quality of each of the video signal output sections; and switches for switching connections between the output terminals and the video signal output sections in accordance with a result of determination made by the decision section. When the decision section has determined the ith (i being a natural number of m or less) video signal output section to be defective, the switches connect the jth (j being a natural number of i−1 or less) video signal output section to the jth output terminal and connect the (k+1)th (k being a natural number of i or more to m or less) video signal output section to the kth output terminal. Thus provided is a driving circuit, capable of self-repairing a defective one of the video signal output sections, which has more simplified wires connected to the video signal output sections.
