Abstract

Disclosed is a liquid crystal display comprising first and second substrates provided opposing one another; a liquid crystal layer made of liquid crystal material that is injected between the first and second substrates; pixel electrodes and a common electrode formed on at least one of the substrates, the pixel electrodes and common electrode generating an electric field that acts on the liquid crystal layer; and domain formation means for controlling a slanting direction of liquid crystal molecules within the liquid crystal layer, wherein m is an integer satisfying the following: h/ 2 (π/ wp ) 1/2 −2≦ m≦h/ 2 (π/ wp ) 1/2 +2 where m is a number of domains formed by dividing the pixel electrodes by the domain formation means, w is a length of a first direction of the pixel electrodes, h is a length of a second direction of the pixel electrodes, the second direction being perpendicular to the first direction, and p is a width of a second direction of the domain formation means.

Claims

exact text as granted — not AI-modified
1 - 18 . (canceled)  
   
   
       19 . A liquid crystal display (LCD) comprising a domain having a long side having a length A and a short side having a length B, wherein A is no shorter than 3B.  
   
   
       20 . The LCD of  claim 19 , wherein the domain has a quadrilateral shape.  
   
   
       21 . The LCD of  claim 19 , wherein the domain is divided by an aperture.  
   
   
       22 . The LCD of  claim 19 , wherein the domain is divided by a protrusion.  
   
   
       23 . The LCD of  claim 19 , wherein the domain is divided by combination of an aperture and a protrusion.  
   
   
       24 . The LCD of  claim 19 , further comprising a plurality of pixels, each pixel being divided into a plurality of domains by a domain divider, 
 wherein m is an integer satisfying the following:        h/ 2(π/ wp ) 1/2 −2≦ m≦h/ 2(π/ wp ) 1/2 +2,    where h is a height of the pixel region, w is a width of the pixel, m is a number of domains formed in the pixel and p is a width of the domain divider.
