1. A display device comprising:
a display panel comprising pixels, each pixel among the pixels comprising sub-pixels; and
an image processor configured to process image data for image display via the display panel,
wherein an arrangement of sub-pixels of a pixel in an odd-numbered pixel column of the display panel is different from an arrangement of sub-pixels of a pixel in an even-numbered pixel column of the display panel such that a pixel in the even-numbered pixel column and one pixel row of the display panel is shifted from a pixel in the odd-numbered pixel column and the pixel row in a vertical direction, and
wherein the image processor comprises:
an edge determiner configured to determine an edge from the image data; and
a sub-pixel renderer configured to perform sub-pixel rendering on pixel data about sub-pixels configured to display a same color in adjacent pixels in the odd-numbered pixel column or the even-numbered pixel column located at the edge.
