Abstract: PURPOSE: A color correcting method for a liquid crystal display device is provided to make a plurality of gray levels having different luminance levels by driving two fields of a frame with different voltages. CONSTITUTION: A color correcting method for a liquid crystal display device includes the steps of making a data table on driving voltage to luminance level(S101), making a table of valid gray levels with respect to luminance levels of the table made in the first step(S102), and obtaining luminance levels(y0,y1) required for improving the gray levels and the number(N) of gray levels required per section(S103). The gray levels calculated in the third step is determined to be linear or not(S104). Otherwise, tolerance factors are applied for shifting voltages of two fields in the increasing and decreasing direction respectively with respect to a voltage(v0) of the lower luminance level, thereby making a lookup table(S105,S106). The lookup table is reconstructed until the gray levels become linear(S107). If the gray levels are already linear, n measurement data are calculated(S108). The measurement data are standardized and an optimum inverse function corresponding to a reference function is selected(S109,S110). Color is corrected by applying the inverse function(S112).
