摘要： PROBLEM TO BE SOLVED: To improve contrast by reducing light leakage on an outer peripheral part (an edge part) of an inclined electrode pattern in an IPS liquid crystal display element.
SOLUTION: The IPS liquid crystal display element has pattern structures formed by making respective interdigital electrodes 2 and signal wires 1 inclined in mutually parallel dog leg shapes wherein the interdigital electrodes 2 are composed of pixel electrodes and common electrodes in a pixel region containing a plurality of signal wires and scanning wires arranged nearly in a matrix, TFT switching elements arranged on respective intersections of the signal wires and the scanning wires, the interdigital pixel electrodes connected to the TFT switching elements and the interdigital common electrodes formed so as to go into engagement with the pixel electrodes. Outer peripheral shapes of the interdigital electrodes 2 and the signal wires 1 formed in the dog leg shapes are constructed with fine steps of staircase shapes wherein the respective steps are constructed with two edges in X- and Y-directions with respect to an optic axis.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display element using a GH liquid crystal adjusted black, wherein a dichroic dyestuff corrects optical spectrum distribution of a wavelength transmitted in a half tone display state of the liquid crystal.
SOLUTION: In the liquid crystal display element, liquid crystal molecules are switched in a plane parallel to substrates by an IPS (In-Plane Switching) display method. The IPS display method is a normally white mode and is characterized in that a GH dyestuff promoting light absorption when voltage is applied by specifying a host liquid crystal and its basic color as black and compensating coloring in the half tone by adjusting the component of the GH dyestuff is mixed in the liquid crystal of a host. The sum total concentration of the GH dyestuff is specified to be 1.0wt.% or less.

摘要： PROBLEM TO BE SOLVED: To perform rubbing treatment so that eccentric unevenness can not be visualized, to eliminate scraping of an alignment layer due to high speed rotation and to eliminate the problem caused by scrapings, in a rubbing alignment treatment device and its method of the alignment layer 5 of a liquid crystal display substrate 3.
SOLUTION: In the device, the length in the circumference direction of a rubbing cloth 1 is made to be a half or below of the outer peripheral length of a rotary roll 2a, the eccentric unevenness generated by a seam of a rubbing roll 2 is made to be hardly visualized and rubbing density is reduced and scraping of the alignment layer is prevented by shortening the length of the rubbing cloth 1.
