Liquid crystal display apparatus

1. A method for providing liquid crystals with a pixel structure having a red pixel, a green pixel, a blue pixel, and a white pixel as a basic unit, the method comprising:

forming, on a substrate, slit electrodes each of having a plurality of slits, each slit electrode corresponding to a respective one of said red pixel, said green pixel, and said blue pixel, such that said liquid crystals corresponding to each of said red pixel, said green pixel, and said blue pixel form a white display having a first chromaticity value; and

forming, in said substrate, another slit electrode having a plurality of slits and corresponding to said white pixel, said liquid crystals corresponding to said white pixel having a chromaticity value that matches said first chromaticity value by said another slit electrode having a slit width, which is a length of each of said slits of said another slit electrode in a length direction, that is adjusted to change said chromaticity value of said liquid crystals corresponding to said white pixel.

2. The method according to claim 1 , wherein

the method is implemented in a fringe field switch (FFS) mode in which a fringe electric field changes an alignment of said liquid crystals,

wherein 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

wherein the method comprises varying said voltage-transmittance characteristics 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 method according to claim 2 , comprising varying said voltage-transmittance characteristics according to a ratio of an arrangement space of each of said slits, which is a distance between each of said slits of said another slit electrode, to said slit width of each of said slits of said another slit electrode.

4. The method according to claim 1 , comprising differentiating a retardation of light that passes through said liquid crystals corresponding to said white pixel 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 method according to claim 3 ,

wherein a resist film is disposed on a display surface side with respect to said liquid crystals, and

wherein the method comprises varying the retardation of the light that passes through said liquid crystals corresponding to said white pixel according to a thickness of said resist film corresponding to said white pixel.

6. The method according to claim 1 ,

wherein a light shielding layer is 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

wherein the method comprises differentiating an area of said opening corresponding to said white pixel from an area of each of said openings corresponding to said red pixel, said green pixel, and said blue pixel.

7. The method according to claim 1 , comprising adjusting said voltage-transmittance characteristics of said liquid crystals corresponding to said white pixel by at least one of a pixel electrode line width and a pixel electrode spacing to be different from voltage-transmittance characteristics of said liquid crystals corresponding to each of said red pixel, said green pixel, and said blue pixel.
