The crosstalk of a display apparatus can be efficiently eliminated to realize a precise, high-quality display. A liquid crystal display apparatus includes, as a crosstalk elimination circuit, an adjacent picture element acquisition circuit () that acquires display signals of picture elements adjacent to a self picture element, and two-dimensional LUTs () that use the display signals of the adjacent picture elements, acquired by the adjacent picture element acquisition circuit (), to correct display signals of the self picture element so as to correct RGB display signals. The picture element display signals as corrected by the correction values output from the LUTs () are output to a source driver () via a timing controlling unit (TC) (). In the crosstalk elimination circuit, the display signals of a picture element to be corrected and those of picture elements adjacent to the picture element that influence the picture element are used to acquire a correction value, thereby correcting the display signals of the correction target picture element.
