摘要： A plurality of reflectors respectively having the same rough reflecting surfaces are formed substantially simultaneously on a transparent substrate of a large area. A photosensitive resin film is formed on a surface of a transparent substrate. An embossing die having a rough working surface is pressed against a photosensitive resin part of the photosensitive resin film and the photosensitive resin part is irradiated with ultraviolet rays from below the transparent substrate to form a prehardened photosensitive resin part. Those steps are repeated to form a plurality of prehardened, embossed photosensitive resin parts on the transparent substrate, and then parts not prehardened of the photosensitive resin film are removed by etching. The prehardened, embossed photosensitive resin parts are heated for hardening, and a metal reflecting film is formed on the hardened embossed photosensitive resin parts to complete a plurality of reflectors.

摘要： A brighter and whiter reflector provides high reflection efficiency over a wide range of angles. An indenting tool is pressed against the surface of a matrix base material; the pressing operation is repeated while changing the position of the indenting tool on the surface of the base material for the matrix to successively form many pits, the inner surfaces of which are shaped like partial spheres, on the mold surface of the matrix base material so as to provide it as the matrix for forming the reflector. Then, a transfer mold having a mold surface which has a reversed pattern of the pits and projections of the mold surface of the matrix is made, and the mold surface of the transfer mold is transferred to the surface of the base material for the reflector to provide a reflector (1). Pits (4) of the reflector (1) are formed so that the depths the pits (4) range from 0.1 &mgr;m to 3 &mgr;m, the tilt angles of the inner surfaces of the pits (4) are distributed in the range of −18 degrees to +18 degrees, and the pitches between adjoining pits (4) range from 5 &mgr;m to 50 &mgr;m. A reflection type liquid crystal display device in accordance with the present invention is equipped with the reflector (1).

摘要： 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.

摘要： The present invention provides a reflector having a light-diffusing property which suppresses inter-object reflection over a wide angle, and giving particularly high reflectance in an intended range of viewing angle; and to provide a reflection type liquid crystal display device using the same. The reflector includes a plurality of light-reflective concave portions. Each of the concave portions is formed so that an inclination angle (an angle between a plane tangential to a point on a concave surface and the surface of the base material) is maximum on a side portion of the curved surface, and so that the direction of the side portion having the maximum inclination angle is on a far side from a view point of an observer. Moreover, the reflector includes many concave portions formed on a reflector surface, an inner surface of each of the concave portions-including a peripheral curved surface and a bottom curved surface that are continuously connected to each other, the peripheral curved surface being a part of a first sphere having a first radius, the bottom curved surface being a part of a second sphere having a second radius different from the first radius, and the bottom curved surface being located within the peripheral curved surface, wherein the first radius is smaller than the second radius, and a normal line extending from a center of the first sphere to the reflector surface and a normal line extending from a center of the second aphere to the reflector surface are not collinear. Further, the reflection type liquid crystal display device is provided with the reflector.
