Organic light emitting diode and organic light emitting device including the same

An organic light emitting device, comprising:

• a substrate;
• and
• an organic light emitting diode positioned on the substrate and including a first electrode, a second electrode facing the first electrode, and a first emitting part including a red emitting material layer and a first hole transporting layer and positioned between the first and second electrodes,
• the red emitting material layer including a first red host and a red dopant, and the first hole transporting layer including a hole transporting material and positioned between the first electrode and the red emitting material layer,
• wherein the first red host is a compound of Formula 1-1:
• wherein each of a, b and c is independently an integer of 0 to 4,
• d is an integer of 0 to 3, and
• at least one of a, b, c and d is a positive integer,
• wherein the hole transporting material is a compound of Formula 3-1:
• and
• wherein:
• each of e, f, g, i and l is independently an integer of 0 to 4,
• each of h, k, m, and n is independently an integer of 0 to 3, and j is an integer of 0 to 5, and
