A refractive index anisotropy value of the liquid crystal layer along a plane parallel to a surface of the liquid crystal cell is smaller in a black display than in a white display. The phase compensation element has three principal refractive indices nx, ny and nz respectively along x, y and z axes thereof which are perpendicular to one another, and when nx and ny are the principal refractive indices along a plane parallel to a surface of the liquid crystal cell with nz being the principal refractive index along a thickness direction of the liquid crystal cell, wherein the x axis is parallel to an absorption axis of one of the polarizing plates closer to a viewer viewing the liquid crystal display device, and the principal refractive indices nx, ny and nz satisfy the following expressions: nz

    摘要： A liquid crystal display device includes a display medium containing at least liquid crystal between a pair of substrates at least one of which is transparent. At least one of the pair of substrates is provided with a film having a concave portion on the side of the display medium. The concave portion has a bottom portion in a vicinity of a center when viewed from a normal direction of the substrate. Liquid crystal molecules contained in the display medium are oriented axisymmetrically around the bottom portion or the vicinity thereof. The contour defining the concave portion in a vertical plane bisecting the bottom portion is a curve and the sign of a second differential of the curve is positive or negative or partially positive and partially negative or the gradient of a surface of the film having the concave portion continuously changes at a border between a pixel portion where the liquid crystal region lies and a non-pixel portion.
