DISPLAY APPARATUS

A liquid crystal panel (11) is provided with: a display section TFT (17), which is disposed on a display section (AA) of an array substrate (11b); a non-display section TFT (29), which is disposed on a non-display section (NAA); a second gate electrode section (29a) constituting the non-display section TFT (29); a second channel section (29d) formed of an oxide semiconductor film (36); a second source electrode section (29b) connected to the second channel section (29d); a second drain electrode section (29c) connected to the second channel section (29d); and a first interlayer insulating film (39), which is laminated at least on the second source electrode section (29b) and the second drain electrode section (29c). The first interlayer insulating film (39) has a laminated structure having laminated therein: a lower layer-side first interlayer insulating film (39a), which is disposed relatively on the lower layer side, and which contains at least silicon and oxygen; and an upper layer-side first interlayer insulating film (39b), which is disposed relatively on the upper layer side, and which contains at least silicon and nitrogen, said upper layer-side first interlayer insulating film (39b) having a film thickness within the range of 35-75 nm.
