Abstract

The invention provides an organic light emitting display device and a manufacturing method thereof. The organic light emitting display device comprises an anode layer, a cathode layer, and a pixel definition layer and a luminous layer which are arranged between the anode layer and the cathode layer, wherein the pixel definition layer is provided with an opening, the luminous layer is arranged in the opening, and a high-refractive index insulating layer of which the refractive index is greater than the refractive index of the pixel definition layer is arranged between the luminous layer and the pixel definition layer. The organic light emitting display device is characterized in that the high-refractive index insulating layer of which the refractive index is greater than the refractive index of the pixel definition layer is arranged between the luminous layer and the pixel definition layer so that light emitted by the luminous layer and transmitted to the pixel definition layer can be totally reflected at the junction of the high-refractive index insulating layer and the pixel definition layer, and therefore, the effect of improving the luminous efficiency of the high-refractive index insulating layer is achieved.
