Liquid crystal display
View Patent ↗A liquid crystal display with better visibility and transmittance. The liquid crystal display includes a first plate having a first field-generating electrode, disposed in a pixel area on an insulating substrate, comprising a plurality of sub-electrodes which are separated from each other by a predetermined distance and arranged parallel to each other, and a connecting electrode electrically connecting the sub-electrodes. An alignment film that is rubbed in a first direction covers a first field-generating electrode and an alignment film that is rubbed in a second direction covers a second field-generating electrode to achieve a predetermined orientation of the liquid crystals when no field is applied and more uniform rotation of the liquid crystal molecules when a field is applied.
1. A liquid crystal display comprising:
a first plate comprising;
a first field-generating electrode, disposed in a pixel area on an insulating substrate;
a plurality of sub-electrodes which are separated from each other by a predetermined distance and arranged parallel to each other, and
a connecting electrode electrically connecting the sub-electrodes; and
a first alignment film covering the first field-generating electrode, wherein the first alignment film has been rubbed in a first direction and directly contacts the connecting electrode;
a second plate comprising;
a second field-generating electrode disposed on an insulating substrate, and a second alignment film covering the second field-generating electrode, wherein the second alignment film has been rubbed in a second direction; and
a liquid crystal layer comprising liquid crystal molecules interposed between the first plate and the second plate,
wherein long axes of the liquid crystal molecules are substantially parallel to the first and second plates.
2. The liquid crystal display of claim 1 , wherein a width of each of the sub-electrodes is 6 μm or less.
3. The liquid crystal display of claim 1 , wherein a distance between the sub-electrodes is in a range between 4 and 14 μm.
4. The liquid crystal display of claim 1 , wherein the first and second alignment films are horizontal-alignment films.
5. The liquid crystal display of claim 1 , wherein the pre-tilt angle of liquid crystal molecules constituting the liquid crystal layer is in a range between 0.5 and 3 degrees.
6. The liquid crystal display of claim 1 , wherein liquid crystal molecules constituting the liquid crystal layer have negative dielectric anisotropy.
7. The liquid crystal display of claim 1 , wherein the first direction and the second direction form an angle of 180 degrees.
8. The liquid crystal display of claim 1 , wherein the sub-electrodes and the first direction form an angle of 60 to 85 degrees.
