1. A display device comprising:
a display panel including a plurality of pixels; and driving means for driving the plurality of pixels, each of the plurality of pixels being constituted by (i) N first sub pixels for displaying different colors and (ii) a second sub pixel(s) for displaying a mixture of colors displayed by any ones of the N first sub pixels, where N is a natural number of two or more, the driving means driving each of the plurality of pixels so that an M first sub pixel(s) of the N first sub pixels is/are driven according to a common gamma curve having a predetermined gamma characteristic, where M is a natural number of 1≦M≦N−1, the driving means driving at least part of the plurality of pixels so that, in each of said at least part of the plurality of pixels, (i) at least part of an N-M first sub pixel(s) is/are driven according to one of first and second gamma curve groups, the one of the first and second gamma curve groups being selected depending on a position(s) where said at least part of the N-M first sub pixel(s) is/are located, and (ii) at least part of a second sub pixel(s) is/are driven according to one of the first and second gamma curve groups, the one of the first and second gamma curve groups being selected depending on a position(s) where said at least part of the second sub pixel(s) is/are located, the first gamma curve group being different from the common gamma curve, the second gamma curve group being different from the common gamma curve and the first gamma curve group.
