A semiconductor device and method of fabricating the device. By using a representational difference analysis adapted for plant genomes, a set of nucleic acid difference sequences between normal and off-type plant genomes are obtained. The counterweight is slidably coupled to the eccentric weight and moves between a first position where the counterweight contacts the eccentric weight and a second position where the counterweight contacts the tubular section. Therefore, enhanced color purity can even be achieved for pixels adjoining one another in the column direction in the delta pixel arrangement. Then the minimum pixel numbers of each level value of Density units Dn-1 and Dn are summed.
