Abstract: A liquid crystal display device, which includes a first substrate and a second substrate disposed to face each other with a liquid crystal sandwiched therebetween. The first substrate is an electrode-provided substrate having a first electrode and a plurality of second electrodes overlaid on the first electrode via an insulating film, formed on a pixel region on a surface on the liquid crystal side, where one of the first electrode and the second electrodes is a pixel electrode and the other is a counter electrode, having a first liquid crystal alignment film formed on the surface on the liquid crystal side of the first substrate covered with the second electrodes. The second substrate is a substrate having a second liquid crystal alignment film formed on a surface on the liquid crystal side, the second liquid crystal alignment film containing a photosensitive side chain type polymer which develops liquid crystallinity.
