    Abstract: A light emitting device includes first and second electrodes facing each other on a substrate, a plurality of stacks stacked between the first and second electrodes and each including an EML so as to emit particular light, and a charge generation layer formed between the stacks so as to adjust charge balance therebetween and including an N-type charge generation layer and a P-type charge generation layer, wherein at least any one of the N-type charge generation layer and the P-type charge generation layer includes the same electron transporting material as that of an electron transport layer of one of the stacks that is adjacent to the N-type charge generation layer.
