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.

Description

technical field [0001] The invention relates to the field of display manufacturing, in particular to an organic light-emitting display device and a manufacturing method thereof. Background technique [0002] With the advancement of display technology, flat panel displays have become the mainstream of applications due to their lightness and thinness. Among various flat panel displays, organic light emitting diode displays (Organic Electro luminescence Display, OLED) and active matrix organic light emitting diode (Active Matrix / Organic Light Emitting Diode, AMOLED) displays are most widely used. [0003] In an OLED light-emitting device, the light emitted from the light-emitting layer passes through each layer of the OLED device and is transmitted to the outside. The light is refracted from one dielectric material to another, such as figure 1 A partial structural schematic diagram of the OLED device shown, the OLED device includes a substrate 101, an electrode 102 disposed on...
