A first pixel, a second pixel, and a third pixel are arranged in the form of matrix in an organic light emitting display device according to the present invention. The organic light emitting display device comprises: a substrate; a gate line formed on the substrate; a data line which is insulated from the gate line and intersects with the gate line; a driving power line which is formed on the substrate and includes a first driving power line supplying a driving voltage to the first pixel, a second driving power line supplying the driving voltage to the second pixel, the a third driving power line supplying the driving voltage to the third pixel; a switching thin film transistor which is connected with the gate line and the data line; a driving transistor which is connected with the switching thin film transistor and the driving power line; a first electrode which is connected with the driving transistor; an organic light emitting member which is formed on the first electrode; and a second electrode which is formed on the organic light emitting member. A cross-sectional area of the first driving power line, a cross-sectional area of the second driving power line, and a cross-sectional area of the third driving power line can be proportional to current consumption of the first pixel, current consumption of the second pixel, and current consumption of the third pixel, respectively. According to the present invention, a variation amount of color coordinates of the first pixel, a variation amount of color coordinates of the second pixel, and a variation amount of color coordinates of the third pixel can be controlled to be the same by allowing cross-sectional areas of the first driving power line, the second driving power line, and the third driving power line to be different from one another, which prevents variation in color coordinates of a white color. |
