In order to restrict a degradation of image quality due to fake contours of moving images, gray scale is displayed by dividing one field period into sub-fields and combining the sub-fields including a plurality of sub-fields weighted such that a light intensity of a certain one of the plurality of the sub-fields is smaller than two times a light intensity of a lower sub-field adjacent to the certain sub-field and larger than the light intensity of the lower sub-field. Further, a light intensity information code converter circuit responsive to binary numbers expressing weights of light intensities of the plurality of the sub-fields for outputting a light intensity information expressing weights in a range satisfying a condition that a light intensity of a certain one of the plurality of the sub-fields is smaller than two times a light intensity of a lower sub-field adjacent to the certain sub-field and larger than the light intensity of the lower sub-field. |
