description The invention provides an organic light-emitting device, a display panel and a display device. The organic light-emitting device comprises a first electrode layer, a hole transport layer, an electron transport layer and a second electrode layer which are sequentially stacked, a plurality of light-emitting units arranged on the same layer are arranged between the hole transport layer and the electron transport layer, and each light-emitting unit comprises a light-emitting auxiliary layer and a light-emitting layer which are sequentially stacked. The light-emitting auxiliary layer is located on one side close to the hole transport layer, the light-emitting unit with the fastest light-emitting response speed in the plurality of light-emitting units is the first light-emitting unit, the green light-emitting unit is the red light-emitting unit, the capacitance-voltage curve integral area of the first light-emitting unit is Q1, and Q1 meets the condition that Qn-Q1 is smaller than or equal to 0.5, and Qn is the cap
