The invention provides a transmission device and a vehicle-mounted ceiling screen. The transmission device comprises a motor, a shaft coupling and a transmission shaft, wherein the motor is provided with a motor shaft; the shaft coupling comprises a first connecting part, a buffer pad and a second connecting part; the motor shaft is connected with one end of the first connecting part, the other end of the first connecting part is connected with one end of the buffer pad, the other end of the buffer pad is connected with one end of the second connecting part, the other end of the second connecting part is connected with the transmission shaft, and the axis of the motor shaft, the axis of the first connecting part, the axis of the buffer pad, the axis of the second connecting part and the axis of the transmission shaft are located on the same straight line. The motor shaft and the transmission shaft are connected through the shaft coupling with the buffer pad, so vibration and noise caused by poor concentricity of a transmission mechanism can be reduced, and the stability and reliability of a transmission system are improved.
