Summary:An optical path adjustment mechanism of projection display is disclosed, which can receive the color light projected from a beam splitter and adjust the optical path of the color light. It comprises: a light valve installed at intervals with the beam splitter, and an adjustment unit. The adjustment unit comprises a fixing base located between the beam splitter and the light valve, and an adjustment base to mount the light valve in a rotational way. By using a simple mechanical structure to vary the angle between the light valve and the fixing base, the present invention has the advantages of adjusting the optical path conveniently and low production cost.
