A liquid crystal projection apparatus includes an illumination system, at least a light-transforming module and a projection lens. The illumination system provides a light beam having light polarized in a first direction and in a second direction. The light-transforming module and the projection lens are both disposed on a transmission path of the light beam. The light-transforming module includes a transmissive liquid crystal display (LCD) panel, a plurality of first polarizers and at least a second polarizer. The light polarized in a first direction passes through the first polarizers disposed at a side of the transmissive LCD panel, and the light polarized in a second direction is partially blocked by each of the first polarizers. The light polarized in the second direction passes through the second polarizer disposed at another side of the transmissive LCD panel, and the light polarized in the first direction is blocked by the second polarizer.
