Abstract: Discussed herein is an organic light-emitting device capable of increasing luminous efficiency and panel efficiency while improving color gamut. The organic light-emitting device includes a red organic light emitting layer including a single host material of hole transport type and a yellow-green organic light emitting layer including a plurality of host materials in a light-emitting stack. Instead of using an additional host material for the organic light emitting layers, the material of the electron transport layer and the material of the hole transport layer is used as the host material of the yellow-green organic light emitting layer, and the material of the hole transport layer is used as the host material of the red organic light emitting layer. Accordingly, the number of materials of the organic light emitting layers is reduced, such that the fabricating process becomes simpler.
