A liquid crystal display panel (2) includes a TFT substrate (20) and a counter substrate (30) placed opposite each other via a liquid crystal layer (40) containing liquid crystal molecules (41) that, when an electric field is applied, makes an alignment transition from an initial state to an image display state different in state of alignment from the initial state. A region (40B) where the liquid crystal molecules come into anti-parallel alignment is provided in that region of at least either the TFT substrate (20) or the counter substrate (30) to which a transverse electric field parallel to a surface of the substrate is applied. This makes it possible to provide a liquid crystal display panel capable of causing each pixel to surely make an alignment transition and making a quick alignment transition from an initial state to an image display state in a liquid crystal layer.
