Patent ID: 8004643

Claim:
A liquid crystal display device comprising: a first substrate and a second substrate which have opposed surfaces respectively provided with aligning films and have undergone aligning treatments such that aligning treatment directions are parallel and opposite between the aligning films; and a liquid crystal layer which comprises a liquid crystal having a negative dielectric anisotropy and is placed between the first substrate and the second substrate such that molecular long axes of the liquid crystal are oriented substantially parallel to surfaces of the substrates, the first substrate including: a first conductive layer on which elongated electrode portions obliquely crossing the aligning treatment direction are formed parallel to each other so as to form slit portions between the adjacent electrode portions, and a second conductive layer which is formed on a layer different from the first conductive layer through an insulating layer so as to overlap the slit portions and overlap at least part of the first conductive layer, wherein the elongated electrode portions each include a first linear portion and a second linear portion which extend in different directions at angles line-symmetrical with respect to the aligning treatment direction, and wherein an angle of one of the first linear portion and the second linear portion with respect to the aligning treatment direction is set to an angle of smaller than 90° and larger than 70°.
