A liquid crystal display panel includes: a plurality of switching elements each provided on a transparent substrate (10) for each sub-pixel and having a source electrode and a drain electrode (14b) spaced apart from each other; an interlayer insulating film (17) provided to cover the switching elements and including an inorganic insulating film (15) and an organic insulating film (16) sequentially layered; a capacitor electrode (18a) provided on the interlayer insulating film (17); a capacitor insulating film (19) provided to cover the capacitor electrode (18a); a plurality of pixel electrodes (20a) which are provided on the capacitor insulating film (19), face the capacitor electrode (18a), and each of which forms an auxiliary capacitor (6) for a corresponding one of the sub-pixels, and is connected to the drain electrode (14b) of a corresponding one of the switching elements, while being insulated from the capacitor electrode (18a), and a connection region (R) at which the drain electrode (14b) and the capacitor electrode (18a) overlap each other via the inorganic insulating film (15) exposed from the organic insulating film (16).
