Liquid crystal display apparatus

Abstract

A liquid crystal display apparatus that controls liquid crystals with a pixel structure having a red pixel, a green pixel, a blue pixel, and a white pixel as a basic unit. Voltage-transmittance characteristics of the liquid crystals corresponding to the white pixel are different from voltage-transmittance characteristics of the liquid crystals corresponding to each of the red pixel, the green pixel, and the blue pixel.

         2 . The liquid crystal display apparatus according to  claim 1 , wherein
 said liquid crystal display apparatus is driven in a fringe field switch (FFS) mode in which a fringe electric field changes an alignment of said liquid crystals,   said red pixel, said green pixel, said blue pixel, and said white pixel each include a slit electrode having a plurality of slits that generate said fringe electric field upon voltage application, and   said voltage-transmittance characteristics vary according to an angle formed between an alignment axis of said liquid crystals and a long-side direction of each of said slits.   
     
     
         3 . The liquid crystal display apparatus according to  claim 2 , wherein said voltage-transmittance characteristics vary according to a ratio of an arrangement space of each of said slits to a length of each of said slits in a short-side direction. 
     
     
         4 . The liquid crystal display apparatus according to  claim 1 , wherein a retardation of light that passes through said liquid crystals corresponding to said white pixel is different from a retardation of light that passes through said liquid crystals corresponding to each of said red pixel, said green pixel, and said blue pixel. 
     
     
         5 . The liquid crystal display apparatus according to  claim 4 , further comprising a resist film disposed on a display surface side with respect to said liquid crystals,
 wherein the retardation of the light that passes through said liquid crystals corresponding to said white pixel varies according to a thickness of said resist film corresponding to said white pixel.   
     
     
         6 . The liquid crystal display apparatus according to  claim 1 , further comprising a light shielding layer disposed on a display surface side with respect to said liquid crystals, wherein
 said light shielding layer has openings formed correspondingly to said red pixel, said green pixel, said blue pixel, and said white pixel, and   an area of said opening corresponding to said white pixel is different from an area of each of said openings corresponding to said red pixel, said green pixel, and said blue pixel.   
     
     
         7 . A liquid crystal display apparatus that controls liquid crystals with a pixel structure having a red pixel, a green pixel, a blue pixel, and a white pixel as a basic unit,
 wherein a retardation of light that passes through said liquid crystals corresponding to said white pixel is different from a retardation of light that passes through said liquid crystals corresponding to each of said red pixel, said green pixel, and said blue pixel.   
     
     
         8 . The liquid crystal display apparatus according to  claim 7 , further comprising a resist film disposed on a display surface side with respect to said liquid crystals,
 wherein the retardation of the light that passes through said liquid crystals corresponding to said white pixel varies according to a thickness of said resist film corresponding to said white pixel.   
     
     
         9 . The liquid crystal display apparatus according to  claim 7 , further comprising a light shielding layer disposed on a display surface side with respect to said liquid crystals, wherein
 said light shielding layer has openings formed correspondingly to said red pixel, said green pixel, said blue pixel, and said white pixel, and   an area of said opening corresponding to said white pixel is different from an area of each of said openings corresponding to said red pixel, said green pixel, and said blue pixel.
