A pixel structure for a flat panel display apparatus displaying images using a plurality of pixels, each of the pixels including six or more sub-pixels. The flat panel display apparatus including the pixel structure is free from a color fringe error, and the pixel can include three or more primary colors. Thus, a color representation range of the flat panel display apparatus can be widened. In addition, since the sub-pixels of the pixel can be controlled by sub-pixel rendering, a resolution of the apparatus can be improved. Moreover, high resolution can be obtained in every direction on the display due to superior rotational symmetry of the pixels.
