Display device having organic light emitting diode with low threshold layer

A display device comprising:

• a plurality of light-emitting regions different in luminescent colors, the plurality of light-emitting regions including a plurality of luminescent layers separated for each of the luminescent colors;
• a low-threshold layer lower, in threshold voltage at which a current flowing therein begins to increase exponentially, than any one of the plurality of luminescent layers included in a pair of different-color light-emitting regions, the pair of different-color light-emitting regions being included in the plurality of light-emitting regions, the pair of different-color light-emitting regions being different in the luminescent colors and being adjacent to each other;
• a continuous layer under the plurality of luminescent layers and the low-threshold layer, wherein the continuous layer is provided in a plurality of first areas and a second area continuously, the plurality of first areas being in contact with the respective plurality of light-emitting regions, the second area being in contact with the low-threshold layer;
• a plurality of pixel electrodes under the continuous layer, the plurality of pixel electrodes overlapping with the respective plurality of light-emitting regions;
• and
• a counter electrode over the plurality of luminescent layers and the low-threshold layer, the counter electrode being opposed to the plurality of pixel electrodes,
• wherein the low-threshold layer is between the pair of different-color light-emitting regions.
