Abstract
The liquid crystal display device of this invention includes a first substrate, a second substrate opposing the first substrate, and a liquid crystal layer sandwiched between the first and the second substrates, wherein the liquid crystal layer includes a polymer region and a liquid crystal domain surrounded by the polymer region in which liquid crystal molecules are oriented in an axial symmetrical manner, the first substrate includes a dry film having a concave portion on a surface facing the liquid crystal layer, and a symmetric axis in the liquid crystal domain substantially extends through the concave portion and is substantially perpendicular to the first substrate.
