A projection display having a dual mode function is provided. The projection display includes: a driving unit controlling an entire operation; a light source unit; a polarization beam splitter splitting light provided from the light source unit into first and second polarized light beams; a first light modulation device located in a path through which the first polarized light beam provided from the PBS (polarization beam splitter), the first light modulation device modulating the first polarized light beam in response to a first image signal and providing the first image; a first projection lens unit magnifying and projecting the first image provided from the first light modulation device; a second light modulation device located in a path through which the second polarized light beam provided from the PBS, the second light modulation device modulating the second polarized light beam in response to a second image signal and providing the second image; and a second projection lens unit magnifying and projecting the second image provided from the second light modulation device. Accordingly, it is possible for the projection display to display two images by using a light source. Thus, it is possible to embody a small display having a dual mode function with low power consumption which is suitable to be used for a mobile device.
