Abstract

The invention discloses an organic light emitting diode and a display device applying the organic light emitting diode, relates to the technical field of electroluminescence, and aims at solving the problem of severe color cast of an OLED device caused by the fact that the light intensity of the present blue light OLED rapidly attenuates along with increasing of the refraction angle. The organic light emitting diode comprises an organic light emitting layer and also comprises a first anisotropic layer. The first refractive index of the first anisotropic layer increases when the first refraction angle formed by the light which is generated by the organic light emitting layer and enters the first anisotropic layer increases. The display device comprises the organic light emitting diode.

Description

technical field [0001] The invention relates to the technical field of electroluminescence, in particular to an organic light emitting diode and a display device using the same. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) has the characteristics of all solid state, self-illumination, high contrast, wide viewing angle, etc. It is the next-generation flat panel display technology after LCD (Liquid Crystal Display, liquid crystal display). [0003] OLED includes a transparent anode, an organic light-emitting layer and a metal cathode. After an appropriate voltage is applied between the anode and the cathode, the holes in the anode and the charges in the cathode will combine in the organic light-emitting layer to generate light. According to the different formulas of the organic light-emitting layer, light of three primary colors of red, green and blue can be generated, thereby constituting light of basic colors.
