ABSTRACT:
A liquid crystal display10of the invention has a transparent substrate11on which are provided multiple signal lines17, scan lines16and auxiliary capacity lines18, plus TFTs and pixel electrodes20that are electrically coupled to the TFTs' drain electrodes D. The auxiliary capacity lines18are formed with an Al—Nd alloy layer coated with a layer of molybdenum. Each pixel region, except for the auxiliary capacity lower electrode18aon the auxiliary capacity line18, is coated over by a first insulating film25and by a second insulating film26that is thinner than the first insulating film25. Further, the auxiliary capacity lower electrodes18aare coated over by the second insulating film26, and auxiliary capacity upper electrodes18bare provided on the surface of the second insulating film26at the auxiliary capacity lower electrodes18a. Thanks to such structure, a small-pixel-area or high-definition liquid crystal display, and manufacturing method therefor, can be provided whereby short circuits in the regions forming the auxiliary capacity are few, the auxiliary capacity is large, and display irregularities such as crosstalk or flicker are satisfactorily curbed.
