A color display panel has an array with a plurality of pixels, each pixel comprises a first sub pixel, a second sub pixel and a third sub pixel, and a red luminescence zone, green luminescence zone and blue luminescence zone. The display panel comprises pixel arrangement of the red luminescence zone, green luminescence zone and blue luminescence zone, which forms a triangle, geometry center of each luminescence zone is positioned at different vertexes of the triangle, such that a side of the triangle substantially is in parallel with on of row direction and column direction, arbitrary luminescence zones bothering with different colors of the row direction are defined to have a distance gap, and arbitrary luminescence zones bothering with different colors of the column direction are defined to have a distance gap, the two gaps distance is substantially or almost equal. The invention can reduce the contraposition difficulty of mask manufacturing technique, besides can increase the opening ratio of the luminescence area of sub pixel, to avoid the color blending circumstance of full color OLED display panel.
