Abstract

The display device of the present invention is provided with a means (8) for setting the writing pulse width of the attentional light-emitting sub-field wider than the normal writing pulse width at all the gray scale levels in the case where at least two continuous non-light-emitting sub-fields possibly exist before the attentional light-emitting sub-field at a certain gray scale level among all the gray scale levels specified on the basis of the number Z of sub-fields and the weighting of the sub-fields. According to the display device of the present invention, the discharge for writing can be stably executed without reducing the number of sub-fields in one field.
