Abstract
A polarized light conversion apparatus comprises a polarization device, a light source, a reflection device and a phase changing device. The polarization device includes a light-transmissible body and a polarization film. The light-transmissible body includes an incidence surface. The incidence surface includes a first part and a second part. The first part intersects the second part at an angle. The polarization film is disposed on the incidence surface. The light source is disposed in one side of a bisector of the angle between the first part and the second part and corresponding to the incidence surface. The reflection device includes a reflection surface. The reflection surface is disposed corresponding to the incidence surface and in the other side of the bisector of the angle. The reflection surface is perpendicular to the bisector of the angle. The phase changing device is disposed between the polarization device and the reflection device.
