Abstract: In a liquid crystal display, first and second substrates are provided opposing each other with a liquid crystal layer held between them, the outer surface of the first substrate serves as a light scattering surface having a light scattering characteristic, and a reflector including an irregular reflection surface is provided on the light scattering surface so that the reflection surface is on the light scattering surface side.

Abstract: Light-reflective concave portions are disposed on the surface of a substrate. The concave portions have a first and second vertical section perpendicular to each other. The first vertical section has an internal shape defined by a first curve and a second curve, the first curve extending from one point on the peripheral edge of the concave portion to the deepest point of the concave portion, and the second curve extending continuously from the first curve and from the deepest point of the concave portion to another point on the peripheral edge of the concave portion. The average of the absolute value of an inclination angle of the first curve is larger than that of the second curve relative to the substrate surface. The second vertical section has an internal shape defined by a shallow curve and deep curves formed at both sides of the shallow curve.

Abstract: A liquid crystal display device includes a reflector disposed at an outside surface side of one substrate of a liquid crystal cell or between the first substrate and an electrode disposed on an inside surface side of the first substrate. When an angle between a direction of a normal line with respect to a display surface of the liquid crystal display device and a main viewing direction is from about 0 degrees to about 20 degrees, a reflection ratio peak value of light incident upon the liquid crystal display device and reflected by the reflector is set so as to occur within a range of about 20 degrees from the normal line direction.

Abstract: A reflector for a liquid crystal display includes a substrate with light-reflective concave portions on the surface thereof. Each concave portion has a specific vertical section which passes through a deepest point of the concave portion. The internal shape of the specific vertical section is defined by a first curve, which extends from one point on the peripheral edge of the concave portion to the deepest point of the concave portion, and a second curve, which extends continuously from the first curve and from the deepest point of the concave portion to another point on the peripheral edge of the concave portion. The average of the absolute value of an inclination angle of the first curve relative to the substrate surface is larger than the average of the absolute value of an inclination angle of the second curve relative to the substrate surface.

Abstract: A reflector and reflector-type LCD suppresses inter-object reflection over a wide angle, and provides particularly high reflectance in an intended range of viewing angle. The reflector includes a plurality of concave portions with an inclination angle (an angle between a plane tangential to a point on a concave surface and the surface of the base material) that is maximum on a side portion of the curved surface. The concave portions may also be formed such that an inner surface of each of the concave portions include a peripheral curved surface and a bottom curved surface are continuously connected to each other. The peripheral curved surface and the bottom curved surface are interposed partial spheres having different radii and non-collinear normal lines from the surface of each sphere.

Abstract: The UV crosslinking compound of the present invention is characterized in having the following chemical formula, and has high photosensitivity. Accordingly, the crosslinking reaction can be accomplished within a short period of time. Thus, if this compound is employed in the alignment film for a LCD component, it becomes possible to carry out a sufficient alignment treatment with UV irradiation over a short period of time. Accordingly, production time can be shortened and production costs reduced. ##STR1## wherein, n is an integer, and X is an atom selected from among F, Cl, Br, I and CN.
