We coated multi-stacked anti-reflective (AR) layer on the glass substrate before deposition of ITO electrode and then fabricated and tested the OLED device. Through the results, it was experimentally found that the emitting efficiency of the OLED device with multi-stacked anti-reflective layer improved than the OLED device without it. Consequently, it was revealed that the external emitting efficiency of OLED device can be improved by deposition of the anti-reflective layer between glass substrate and ITO electrode. It was also found that the device can be easily fabricated without vacuum break by employing existing thermal evaporation.
