<p>Provided are a circuit board, which is provided with a contact hole, and which has a sufficiently improved aperture ratio, a circuit board manufacturing method, and a display apparatus. This circuit board is provided with a first electrode (SD) and a second electrode (Pixel), which are provided on different layers, the circuit board is provided with a contact hole (CH), which electrically connects the first electrode and the second electrode to each other, and in a cross-sectional view of the circuit board, an organic insulating film (JAS) and an inorganic insulating film (Pas2), which is provided on the organic insulating film, are provided between a layer having the first electrode provided thereon, and a layer having the second electrode provided thereon. The organic insulating film is configured of, as an essential material, a chemically amplifying type material that generates acid when light for patterning the organic insulating film is applied thereto.</p> |
