1. a liquid crystal projection apparatus, is characterized in that, comprising:

  • Light source cell has first, second, and third laser instrument of launching respectively redness, green and blue laser beam, and described first, second, and third laser instrument is all semiconductor laser or solid-state laser;

    LCD panel, the liquid crystal layer that wherein consists of redness, green and blue pixel is formed between light incident side substrate and exiting side substrate, and the microlens array that is comprised of many lenticules is formed on the light incident side substrate;

    Beam divergence and shaping optical element, come scattering and shaping from the versicolor laser beam of described light source cell emission by optical diffraction or refraction, make versicolor laser beam all whole viewing areas of covering liquid crystal display, and incide on the respective pixel of described liquid crystal layer of described LCD panel;

    Lens combination will be converted to the light beam that each collimates substantially by the versicolor laser beam of beam divergence and the scattering of shaping optical element and shaping, make light beam incide on the described lenticule of described LCD panel;

    WithProjecting lens is used for projection by the image light of described LCD panel,Wherein, each laser beam from the versicolor laser beam of described light source cell emission has a beam diameter, and this beam diameter is chosen as to make from the corresponding light beam of described beam divergence and the outgoing of shaping optical element to have with respect to the xsect that a bit forms 1 degree or the less angle of divergence on described LCD panel.
