A laryngoscope with automatic image adjustment is revealed. The laryngoscope includes a laryngoscope body, a rotation assembly, a display and a sensor. The laryngoscope body is disposed with a fixing slot and is used for capturing an image. One end of the rotation assembly is fixed in the fixing slot while the other end thereof is arranged with the display. The display is rotated around the rotation assembly. The rotation assembly is set with a limiting slot. The sensor is electrically connected to a rear side of the display and is located inside the limiting slot. While the display being rotated, the sensor is slid on the surface of the rotation assembly. When the sensor is slid in the limiting slot, the display shows the image. Once the sensor is slid outside the limiting slot, the display shows a reflection of the image. Thus the image is adjusted automatically.
