PURPOSE: A look up table manufacturing method for driving an electrophoretic display device is provided to improve the quality of an image displayed by the electrophoretic display device by manufacturing a look up table that is capable of preventing a charge property of a charge carrier from being varied. CONSTITUTION: A first driving value for converting a first image with an N grayscale into a second image with an M grayscale is configured(S10). A second driving value for converting a first image with an N+1 grayscale into a second image with an M grayscale is configured(S20). A third driving value for converting a first image with an N grayscale into a second image with an M+1 grayscale is configured(S30). The first driving value is reduced from the second driver value and the third driving value is added to the second driving value. A calculation driving value for converting the first image with an (N+1) grayscale into the second image with an (M+1) grayscale is generated(S40). [Reference numerals] (S10) Setting a first driving value for converting an N grayscale into an M grayscale; (S100) Generating reference driving values; (S20) Setting a second driving value for converting an (N+1) grayscale into the M grayscale; (S200) Generating driving values included in a diagonal area; (S30) Setting a third driving value for converting the N grayscale into an (M+1) grayscale; (S40) Generating an operation driving value for converting the (N+1) grayscale into the (M+1) grayscale; (S400) Setting driving values included in a first area as conversion driving values; (S500) Generating driving values included in a second area by the symmetrical conversion driving values; (S51) Grayscale of a first image corresponding to the operation driving value is the maximum grayscale?; (S52) Adding 1 to N; (S61) (M+1) grayscale is a (maximum-1) grayscale?; (S62) Adding 1 to M; (S63) Setting a start value of the N as (M+1)
