Abstract: The present disclosure relates to an organic light emitting transistor, a display panel and a display apparatus. At least part of a first micro-nano grating structure is provided on a side of the electron transport layer away from the base substrate, such that at least part of a second micro-nano grating structure is provided on a side of the first electrode away from the base substrate. The first micro-nano grating structure and the second micro-nano grating structure can reduce the wave vector in the waveguide effect plane, thus effectively reducing the wave vector in the plane. When the wave vector in the plane is smaller than the wave vector in the free space, the plasma mode will be excited to convert into an emittable mode, thus effectively extracting the emitted light.
