WHITE LIGHT EMITTING DEVICE AND LIGHT EMITTING APPARATUS INCLUDING THE SAME

摘要

A blue organic light emitting layer is formed between electrodes to be as a light source. A substrate includes red and green florescent substances. The prevent invention secures white light by independently forming layers without mixing at least two-wavelength florescent substances, thereby easily controlling color temperature, preventing the deterioration of light emitting materials to obtain superior color stability, extending the life, and securing high color rendition.
