A correction characteristic determining device provided with (a) data converting means for converting measured data, indicative of an emission condition of a liquid crystal panel, into brightness data of three primary colors by using a conversion matrix, and (b) correction characteristic determining means for determining the correction characteristic in accordance with a conversion result obtained by the data converting means, and may further include conversion matrix generator for generating a conversion matrix. Thus, it is possible to provide the correction characteristic determining device which matches a correction characteristic of a liquid crystal device to a characteristic of a liquid crystal panel.
