1. A display apparatus, comprising: a display panel having a plurality of pixels, each of pixels including a plurality of sub-pixels disposed according to a delta arrangement; a subtractive color processing circuit generating subtractive color image data in response to input image data indicative of gradation associated with the sub-pixels; and a driving circuit driving the display panel in response to the subtractive color image data, wherein the subtractive color processing circuit performs an error diffusion processing and a weighting processing for the input image data, performs weighting processing so as to increase or decrease a value of the subtractive color image data according to a line including the sub-pixel subjected to the subtractive color processing, a value of the subtractive color image data corresponding to a sub-pixel which belong to a first line increases upon displaying a frame, and a value of the subtractive color image data corresponding to a sub-pixel which belongs to a second line adjacent to the first line upon displaying the frame.
