The optical engine module includes a light valve, a casing, and a heat conducting structure. The light valve is configured to convert the illumination beam into an image beam. The light valve has a front portion and a rear portion opposite to each other. The casing is connected to the front portion. The heat conducting structure is disposed on the casing and at at least one side of the front portion. The projection lens is disposed on the casing and configured to project an image. The heat conducting structure is configured to dissipate heat of the casing and the front portion of the light valve.
