- the organic light emitting diodes of Examples 1-1 to 1-6 manufactured by using a spiro type compound according to an exemplary embodiment of the present specification have a lower voltage and higher efficiency than those of Comparative Example 1-1, which are benzidine-type materials. It can be seen that it exhibits characteristics.
- a glass substrate (corning 7059 glass) coated with ITO (Indium Tin Oxide) with a thickness of 1,000 ⁇ was placed in distilled water in which a dispersant was dissolved, and ultrasonically washed. Fischer Co. products were used for the detergent, and Millipore Co. Secondly filtered distilled water was used as a filter of the product. After the ITO was washed for 30 minutes, the ultrasonic cleaning was repeated twice with distilled water for 10 minutes. After washing the distilled water, the ultrasonic washing in the order of isopropyl alcohol, acetone, methanol solvent and dried.
- ITO Indium Tin Oxide
- Hexanitrile hexaazatriphenylene was thermally vacuum deposited to a thickness of 500 kPa on the prepared ITO transparent electrode to form a hole injection layer.
- HT1 900 kPa
- Compound 2 was vacuum deposited at a film thickness of 100 kPa on the hole transport layer to form a hole control layer.
