Patent ID: 8421976

Claim:
A liquid crystal display device comprising: a first substrate including a strip-shaped main pixel electrode having a first width in a first direction and linearly extending in a second direction crossing the first direction, the main pixel electrode including a first edge extending in the second direction, the first substrate further including a sub-pixel electrode crossing the main pixel electrode and protruding from the first edge in the first direction, and a first alignment film covering the main pixel electrode and the sub-pixel electrode; a second substrate including main common electrodes extending substantially parallel to the main pixel electrode on both sides of the main pixel electrode, and a second alignment film covering the main common electrodes; and a liquid crystal layer including liquid crystal molecules held between the first substrate and the second substrate, wherein the sub-pixel electrode has a second width, which is greater than the first width, in the first direction, has a third width, which is a maximum width in the first direction, at a central portion of the sub-pixel electrode, has a fourth width in the second direction at a position with a first distance from the first edge in the first direction, and has a fifth width, which is less than the fourth width, at a position with a second distance, which is greater than the first distance, from the first edge in the first direction, and the first substrate further includes a gate line and a storage a capacitance line which extend in the first direction, and a first shield electrode which is set at the same potential as the main common electrodes, extends in the first direction, is opposed to the gate line, and is covered with the first alignment film.
