Disclosed is an organic light-emitting display device, which prevents lateral current leakage by providing a structure on a bank so as to cut off an organic material, which is formed in a subsequent process, around the structure.

Organic light-emitting display device with spacer between sub-pixels

Disclosed are an organic light emitting diode, an organic light emitting diode display device and a display device for vehicles using the same. The organic light emitting diode may achieve process simplification and reduction in material costs while maintaining high luminance, through structure change.
