Abstract: An organic compound having a tetraphenyl moiety and at least one fused hetero aryl moiety having at least one oxygen and/or sulfur on a ring and bonded to the tetraphenyl moiety directly or indirectly, and a light emitting diode and a light emitting device having the organic compound are disclosed. The organic compound has excellent thermal resistance property and hole mobility property. The organic compound can be incorporated into a hole transfer layer, an electron blocking layer and/or a charge generation layer of the light emitting diode. Therefore, the light emitting diode and light emitting device according to the present invention have decreased driving voltage and enhanced luminous efficiency.
