Abstract

Discussed is an organic light emitting display device including a plurality of pixels, where red sub pixels and blue sub pixels of adjacent pixels are aligned in a first direction and are also aligned in a second direction, the second direction being a direction that intersects the first direction. Also, the green pixels of adjacent pixels are aligned in the first direction and are also aligned in the second direction. And the at least one green sub pixel of each pixel is disposed between the at least one red sub pixel and the at least one blue sub pixel of the each pixel, and the at least one green sub pixel is offset from the at least one red sub pixel and the at least one blue sub pixel in the first direction and the second direction in the each pixel.
