Liquid crystal display device

1. A liquid crystal display device which is configured such that a liquid crystal layer including liquid crystal molecules having negative dielectric constant anisotropy is held between a first substrate and a second substrate, comprising:

pixel electrodes which are disposed in association with a plurality of pixels which are arrayed in a matrix, in the first substrate;

a first alignment film which covers the pixel electrodes and aligns the liquid crystal molecules in a direction substantially perpendicular to the first substrate;

light-blocking wiring lines which cross the pixel electrodes and are formed of a light-blocking, electrically conductive material;

a counter-electrode which is disposed in common with the plurality of pixels, in the second substrate;

a second alignment film which covers the counter-electrode and aligns the liquid crystal molecules in a direction substantially perpendicular to the second substrate; and

a slit portion which controls an alignment direction of the liquid crystal molecules in a manner to form a multi-domain in each of the pixels, and is formed in the pixel electrode or the counter-electrode,

wherein the slit portion includes

a first slit portion which extends parallel to the light-blocking wiring line and overlaps the light-blocking wiring line, and

a second slit portion which is substantially perpendicular to the first slit portion, extends parallel to a long side of the pixel electrode, is shorter than the long side of the pixel electrode, and is narrower than the first slit portion,

wherein the first slit portion and the second slit portion cross at a substantially central part on the pixel electrode, and

wherein the first slit portion is formed in the counter-electrode, and crosses the pixel electrodes disposed on the plurality of pixels.
