    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.

    摘要： According to the present invention, a display medium layer is sandwiched between a TFT substrate and a counter substrate. In the display medium layer, resin walls are respectively formed in regions other than those where a plurality of segmented electrodes are formed, and liquid crystal portions are respectively formed in regions between the respective resin walls, corresponding to those where the segmented electrodes are formed. Disclination lines are formed on the interfaces between the resin walls and the liquid crystal regions. In a liquid crystal display device, liquid crystal molecules in the liquid crystal regions are radially oriented and at least one liquid crystal domain is formed in each liquid crystal region.

    摘要： A liquid crystal display device of the present invention includes: a liquid crystal cell having a pair of substrates and a liquid crystal layer interposed therebetween; a pair of polarizing plates interposing the liquid crystal cell therebetween; and a phase compensation element provided between at least one of the polarizing plates and the liquid crystal cell. 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
