ACTIVE MATRIX SUBSTRATE AND LIQUID-CRYSTAL DISPLAY DEVICE

摘要

Provided is a TFT substrate (10) comprising: a substrate (10a); a TFT (11) that is supported by the substrate; a scanning wiring line (12); a signal wiring line (13); a first interlayer insulating layer (15) provided so as to cover the TFT; a pixel electrode (16) that is electrically connected to a drain electrode (11d) of the TFT; and a transparent auxiliary capacitance electrode (17) provided so as to overlap with at least a portion of the pixel electrode. A contact hole (CH) for electrically connecting the pixel electrode to the drain electrode is formed at least in the first interlayer insulating layer. The scanning wiring line has a first region (R1) that branches into two branched wiring lines (12a). The contact hole is arranged between the two branched wiring lines.
