Abstract: Provided are a reflective liquid crystal display device and a liquid crystal display unit capable of eliminating or minimizing the occurrence of misalignment specific to a vertically aligned liquid crystal due to the structure of a pixel groove and achieving higher contrast and superior image quality. In a reflective pixel electrode (42), a peripheral portion is inclined, and the reflective pixel electrode has a trapezoidal shape so that the width of the reflective pixel electrode (42) increases from the top side to the bottom side. When a side surface of the reflective pixel electrode (42) is inclined so as to eliminate verticality in a cross section of the reflective pixel electrode (42), liquid crystal molecules aligned in a horizontal direction to an extreme in a pixel groove portion can be eliminated. Even if liquid crystal molecules are locally and slightly aligned in a horizontal direction, sufficient verticality can be maintained in the pixel groove portion by an interaction with vertically aligned liquid crystal molecules around the horizontally aligned liquid crystal molecules.

Abstract: A liquid crystal material comprises negative-type mesogen(s) comprising soluble, dipolar dopant(s). Independent claims are also included for: (1) a method of producing a liquid crystal material by mixing negative-type mesogen(s) with a soluble, dipolar dopant; (2) a method of producing liquid crystal cells or negative-type crystal displays by mixing negative-type mesogen(s) and 0.01-10 wt.% soluble, dipolar dopant(s), centrifuging the mixture, filling cells with the mixture, and annealing the filled cells; and (3) a method of improving the response times, homogeneous on-state alignments and contrast of a negative-type liquid crystal material without degrading the off-state, by adding soluble, dipolar dopant(s) to the liquid crystal material.

Abstract: A magnetic head comprising a magnetic path (1) and a vertically magnetizable film (3). The magnetic path contains a first gap (G1) facing a magnetic recording medium (5) and a second gap (G2). The vertically magnetizable film (3) is formed across the second gap (G2) on the principal plane or outer circumference of the magnetic path (1). A linearly polarized light beam is irradiated onto the vertically magnetizable film and the resulting reversal of magnetization in the vertically magnetizable film is detected through the use of a polar Kerr effect. This scheme allows data to be reproduced with sufficient sensitivity from tracks of very small widths.
