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.

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： A reflector and a liquid crystal display device in which original reflection characteristics can be sufficiently accomplished and moiré patterns can be prevented are provided. A reflector 30 formed with a plurality of concave portions 28b1, 28b2 on one surface of a base member along one arrangement direction is employed. When defining the section passing through the deepest point of the concave portion as a first section and defining the section perpendicular to the first section at the deepest point as a second section, the concave portions 28b1, 28b2 have symmetrical shapes on the basis of the first section and have asymmetrical shapes on the basis of the second section. When defining the directions along the first section in the concave portions 28b1, 28b2 as axis directions L1, L2, each of the axis directions L1, L2 are not parallel with the arrangement direction, and the axis directions L1, L2 are set to two or more directions.

摘要： An opening formed on a transflective film is close to the edge of a rectangular pixel region. An interval t2 between three sides of the four sides of the opening and the edge of the pixel region is smaller than the width of one concave portion formed on the transflective film thereby permitting the concave portions that contribute the least to reflection to be minimized, and the reflectance of the transflective film to be maximized. The desired reflection characteristic can be obtained using a predetermined number of concave portions.

摘要： When the thickness of a filter layer 170 in a light-reflecting portion R (the thickness of a thin portion 170a) is ‘FR’, the thickness of the filter layer 170 in a light-transmitting portion T (the thickness of a thick portion 170b) is ‘FT’, the thickness of a liquid crystal layer 150 in the light-reflecting portion R is ‘LR’, the thickness of the liquid crystal layer 150 in the light-transmitting portion T is ‘LT’, and the depth of a groove 155 is ‘D’, the depth D of the groove 155 formed in a resin layer 160 is formed to satisfy the formula D=(LT−LR)+(FT−FR). With defining (LT−LR) as ‘L’ and (FT−FR) as ‘F’, the formula becomes D=L+F. If the depth of the groove 155 satisfies the formula, it is possible to make an optical path length of external light N equal to an optical path length of illumination light B from a backlight 200 when they pass through the liquid crystal panel.

摘要： 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.
