A flat panel display with good color mixture of three primary colors to achieve different hues and little signal delay is provided. The display includes signal lines including scan lines and data lines intersecting the scan lines, both arranged along straight lines. Red, green, and blue pixel driving circuit regions are defined by the intersection of the scan lines and the data lines. The pixel driving circuit regions having the same color are arranged adjacent to one another along a column direction. Red, green, and blue pixel driving circuits are placed in the pixel driving circuit regions and are coupled to the red, green, and blue pixel electrodes. The pixel electrodes are adjacent to pixel electrodes of a different color along both row and column directions.
