A display device includes a PDP having sub-pixels (C) arranged in a delta
configuration and driven by a sub-field gradation method. In an
odd-numbered field, three sub-pixels (C22, C31, C33) constitute one pixel
(P) (in a first display mode). In an even-numbered field, three sub-pixels
(C31, C33, C42) constitute one pixel (P) (in a second display mode). The
pixel (P) including the sub-pixel (C31) for emitting red (R) and the
sub-pixel (C33) for emitting blue (B) selects the sub-pixels (C22, C42)
alternately as the sub-pixel (C) for emitting green (G) on a
field-by-field basis. This displaces the position of the pixel (P) field
by field.
