Disclosed are a projection system and method for a reflection-type liquid crystal display (LCD). The projection method of the reflection-type LCD includes the steps of selectively transmitting a beam in white light, sequentially converting the selectively transmitted beam into R/G/B light and dividing the converted light into an S-polarization beam and a P-polarization beam, a reflection-type LCD receiving the polarized beam and driving liquid crystal for each pixel to thus realize a screen and enlarging the thus realized image and projecting the enlarged image to the screen through a projection lens system, and applying a reset voltage to the reflection-type LCD and forcibly displaying an entire screen to be black before displaying the next screen when a screen is displayed. It is possible to improve the brightness of an entire system by providing a reset state where the reflection-type LCD driven in a white mode in a normal state among single panel reflection-type LCDs displays an entire screen to be black before displaying the screen. It is possible to reduce an off-time which is a problem in the white mode because a panel that operates in the white mode in the normal state operates like a panel that operates in a black mode in the normal state. Accordingly, it is possible to improve light efficiency and to reduce light leakage.
