Patent ID: 7675596

Claim:
An LCD device including a first substrate having a common electrode, a second substrate having pixels arranged in a matrix form, and a liquid crystal layer interposed between the first substrate and the second substrate, a transmission part and a reflection part being included in each of the pixels, the LCD device comprising: a first linear dielectric protrusion disposed between the common electrode and the liquid crystal layer so as to extend over a plurality of pixels in a short side direction of pixels, said first linear dielectric protrusion being disposed nearly in center of the transmission part; and a second linear dielectric protrusion disposed in the reflection part between the common electrode and the first substrate so as to extend over a plurality of pixels in the short side direction of pixels, wherein an alignment direction of liquid crystal molecules crosses said first and second linear dielectric protrusions at right angles, and the alignment direction of the liquid crystal molecules is parallel to a long side direction of pixels, and a tilt angle of the liquid crystal molecules is approximately 0 degree, or even if there is a pre-tilt angle, the tilt angle of the liquid crystal molecules is 2 degrees or less.
