Claim:
1. A grayscale value setting method for a liquid crystal panel comprising a plurality of pixel units, each of which comprises a main pixel area M and a sub pixel area S, wherein, an area ratio of the main pixel area M and the sub pixel area S is a:b, the method comprising: S S S wherein, actual luminance values LvMα and LvMβ of each grayscale G of the main pixel area M at the front view angle α and the slant view angle β are obtained, respectively; actual luminance values LvSα and LvSβ of each grayscale G of the sub pixel area S at the front view angle α and the slant view angle β are obtained, respectively; S S and judging: wherein, when the condition Gmx≧Gm(x−1), Gsx≧Gs(x−1) is satisfied and y is minimal, corresponding grayscales Gmx and Gsx are set to be grayscales respectively input to the main pixel area M and the sub pixel area S when the pixel unit is at the grayscale Gx; and S
