A liquid crystal display 10 of the invention has a transparent substrate 11 on which are provided multiple signal lines 17 , scan lines 16 and auxiliary capacity lines 18 , plus TFTs and pixel electrodes 20 that are electrically coupled to the TFTs' drain electrodes D. The auxiliary capacity lines 18 are formed with an Al-Nd alloy layer coated with a layer of molybdenum. Each pixel region, except for the auxiliary capacity lower electrode 18 a on the auxiliary capacity line 18 , is coated over by a first insulating film 25 and by a second insulating film 26 that is thinner than the first insulating film 25 . Further, the auxiliary capacity lower electrodes 18 a are coated over by the second insulating film 26 , and auxiliary capacity upper electrodes 18 b are provided on the surface of the second insulating film 26 at the auxiliary capacity lower electrodes 18 a. 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.
