## Abstract

A pixel arrangement of color display panel includes a plurality of first sub-pixels, second sub-pixels, third sub-pixels and fourth sub-pixels for respectively providing a first color light, a second color light, a third color light and a fourth color light. The first sub-pixels and the fourth sub-pixels respectively have the same first length and fourth length in a first direction. The second sub-pixels and the third sub-pixels respectively have the same second length and third length in the first direction, which are greater than the first length. The first and fourth sub-pixels are arranged along the first direction to form sub-pixel columns, wherein one of the first sub-pixels in one of the sub-pixel columns partially overlaps one of the first sub-pixels and one of the fourth sub-pixels in another sub-pixel column in a second direction perpendicular to the first direction.
