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

摘要

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.
