A component including a part having a concave and convex configuration for one of the enabling one of light convergence, light diffusion and light diffraction, being formed as a reflective film. The outline of the concave and convex configuration viewed from a right angle relative to a horizontal face has a half moon-shape, and a direction of a straight line part of the half moon-shape of each concave and convex configuration matches a direction of the horizontal face, and a plurality of the concave and convex configurations are combined.

Microlens array, a method for making a transfer master pattern for microlens array, a concave and convex pattern obtained from the transfer master pattern, a laminate for transfer, a diffuse reflection plate and a liquid crystal display device

A microlens array having a substrate and microlenses of a substantially circular profile provided on the substrate and each arranged such that a major axis and a minor axis thereof, which pass through a center of the substantially circular profile and intersect at 90 degrees, are substantially equal in length to each other, and sectional forms at faces vertical to an axis parallel to the major axis or the minor axis are, respectively, made of the same curved shape at any position.

MICROLENS ARRAY, A METHOD FOR MAKING A TRANSFER MASTER PATTERN FOR MICROLENS ARRAY, A CONCAVE AND CONVEX PATTERN OBTAINED FROM THE TRANSFER MASTER PATTERN, A LAMINATE FOR TRANSFER, A DIFFUSE REFLECTION PLATE AND A LIQUID CRYSTAL DISPLAY DEVICE

A microlens configuration having a substantially circular form is constituted of a part of one circle or aspheric curve at any section when a section is taken at a face which is vertical to a major axis or a minor axis of the microlens configuration. A laminate for transfer includes a concave and convex pattern having concave and convex forms of a transfer master pattern, in which a number of such configurations as mentioned above are arranged, transferred to a substrate to be transferred, and a thin film layer laminated on the concave and convex surface thereof wherein a surface of the thin film layer opposite to a surface in contact with a provisional support is used as a bonding face to an application substrate. Moreover, a method for making a diffuse reflector plate comprises the steps of holding the laminate for transfer against the application substrate in contact with the bonding face of the thin film layer, separating the provisional support, and forming a reflective film on the concave and convex surface of the thin film layer.
