A displaying method of a digital light processing (DLP) projector includes the steps of: providing a light modulation device including a driver printed circuit board and a digital micromirror device (DMD), wherein the DMD includes a plurality of micromirrors each having a first stable state and a second stable state, and a predetermined light incident direction, the DMD is installed on the driver printed circuit board; providing an illumination light beam being incident on the DMD along an operating direction different from the predetermined light incident direction, modulating the illumination light beam to an imaging light beam by the DMD and directing the imaging light beam to a projection lens for projecting an image. A DLP projector made thereby has a relatively lower manufacturing cost.
