摘要：
An active matrix drive type liquid crystal display element capable of preventing deterioration of display capability caused by a stripe domain, and a projection type display device using the liquid crystal display element, by which there is provided a projection type display device comprising a light source; a light convergence optical system for guiding a light emitted from said light source to a liquid crystal display element; and a projection optical system for enlarging and projecting a light subjected to light modulation by said liquid crystal display element; wherein the liquid crystal display element is configured by holding a liquid crystal layer between a pair of substrates arranged to face to each other, and a twisted nematic type liquid crystal material used in the liquid crystal layer satisfies dielectric constant anisotropy Δε of 0 6.0 pN when the refractive index anisotropy Δn is 0.16≦Δn≦0.18 and satisfies dielectric constant anisotropy Δε of 0 3.0 pN when the refractive index anisotropy Δn is 0.18≦Δn≦0.20.
