Display device

A display device comprising:

• a display unit in which a plurality of sub-pixels are arranged in a matrix along row and column directions;
• and
• a signal processor configured to output output signals for causing the display unit to display an image based on input signals for the image in which pixel data including three colors of red, green, and blue is arranged in a matrix,
• wherein the sub-pixels comprise a first sub-pixel for red, a second sub-pixel for green, a third sub-pixel for blue, and a fourth sub-pixel for white,
• wherein either the first sub-pixel or the third sub-pixel is interposed between the second sub-pixel and the fourth sub-pixel arranged in one direction of the row direction and the column direction,
• wherein the signal processor is configured to output the output signals to assign, to a set of the sub-pixels included in the display unit, color components assigned to two pieces of the pixel data arranged in the one direction in the input signals,
• wherein the set of the sub-pixels is made up of the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel, and
• wherein the signal processor is configured to assign a first color component to the fourth sub-pixel and second color components to the first sub-pixel, the second sub-pixel, and the third sub-pixel, the first color component being a part or the whole of a white component included in one piece of the pixel data among the color components included in the two pieces of the pixel data, the second color components being components other than the first color component of the color components included in the two pieces of the pixel data.
