The invention provides a transmission device and a vehicle-mounted ceiling screen. The transmission device comprises a motor, a coupler, a flexible shaft and a transmission shaft, wherein the motor isprovided with a motor shaft; the motor shaft is connected with one end of the coupler; the other end of the coupler is connected with one end of the flexible shaft; the other end of the flexible shaft is connected with the transmission shaft; and the axes of the motor shaft, the coupler, the flexible shaft and the transmission shaft are located on the same straight line, and the transmission device is connected with the motor shaft and the transmission shaft through the combination of the coupler and the flexible shaft. Vibration and a noise caused by poor concentricity of a transmission mechanism can be reduced, and stability and reliability of a transmission system are improved.
