PROBLEM TO BE SOLVED: To provide an organic EL device aiming at prolongation of life, which can be easily manufactured and controlled, and a manufacturing method of the same. SOLUTION: The amount of the light emitted from whole of light emitting areas 14R, whole of light emitting areas14G and whole of light emitting areas 14R are differentiated from each other by differentiating the number of light emitting areas 14R, 14B, and 14B in a pixel area K. The state of colors having larger number of light emitting areas, for instance, those of the light-emitting areas 14R and the light-emitting areas 14B are nearly equal to the state wherein, aperture ratio is practically increased, therefore, sufficient amount of light can be irradiated from whole of the light emitting areas 14R and 14B even if the amount of light emitted from individual light emitting areas R14 and B14 are reduced, With this, stress on the light emitting areas 14R and 14B having life shorter than that of the light emitting areas 14G can be restrained, and prolongation of life can be aimed at.
