Abstract

A liquid crystal display device including a first substrate on which a first electrode and a bus line for transmitting a signal to the first electrode are formed; a second substrate on which a second electrode is formed; and domain defining projections provided on one of the first substrate and the second substrate. A plurality of domain defining slits are provided on the electrode on the other of the first substrate and the second substrate to be aligned on a straight line, and liquid crystal having negative dielectric anisotropy is sealed between the first substrate and the second substrate. A width of a bus line opposite side end of a first slit of the plurality of slits, that is positioned closest to the bus line, is set smaller than a width of a bus line side end of a second slit positioned adjacent to the first slit.

Claims (9)

1. A liquid crystal display device comprising:

a first substrate on which a first electrode and a bus line for transmitting a signal to the first electrode are formed;

a second substrate on which a second electrode is formed;

domain defining projections provided on one of the first substrate and the second substrate;

a plurality of domain defining slits provided on the electrode on the other of the first substrate and the second substrate to be aligned on a straight line; and

liquid crystal sealed between the first substrate and the second substrate and having negative dielectric anisotropy;

wherein a width of a bus line opposite side end of a first slit of the plurality of slits, that is positioned closest to the bus line, is set smaller than a width of a bus line side end of a second slit positioned adjacent to the first slit.

2. A liquid crystal display device according to claim 1 , further comprising:

auxiliary projections provided on one substrate to be arranged along the edge of the electrode on the other substrate.
