In a vertical alignment mode liquid crystal display device, orientation control with an oblique electric field is stably performed, and decrease in light transmittance is suppressed without much increase in the number of production steps. A liquid crystal display device according to the present invention includes a first substrate, a second substrate provided so as to oppose the first substrate, and a vertical-alignment type liquid crystal layer provided between the first substrate and the second substrate, and has a plurality of pixels each including: a switching element which is provided on the first substrate and at least includes a semiconductor layer; a pixel electrode electrically connected to the switching element; a counter electrode opposing the pixel electrode; and the liquid crystal layer interposed between the pixel electrode and the counter electrode. The pixel electrode includes at least one recessed portion (or aperture) formed at a predetermined position in the pixel, and in each of the plurality of pixels, when at least a predetermined voltage is applied across the liquid crystal layer, a plurality of regions are created where liquid crystal molecules tilt in respectively different azimuthal directions. The first substrate includes an auxiliary electrode to which a different potential from that for the pixel electrode is applied. The auxiliary electrode includes a portion overlapping the recessed portion (or aperture) of the pixel electrode, and is made of the same film as the semiconductor layer of the switching element.
