Problems solved by technology
[0009] Therefore, if a micro-concave-convex pattern is formed using a resin whose glass transition temperature is low and heat resistance is not yet completed, and the reflective film 26 is coated and fired, when polyimide is used for the alignment film 36, then There is a problem that the micro-concave-convex pattern is damaged in the sintering process of the alignment film 36 formed of polyimide having high heat resistance and glass transition temperature

Embodiment Construction
[0075] Preferred embodiments of the present invention will be described in detail below by way of example with reference to the drawings. Dimensions, materials, shapes, relative arrangements, and the like of components described in this embodiment do not limit the scope of the present invention unless otherwise specified, and are merely illustrative examples.
[0076] 1A to 1G are explanatory views of a method of forming a concave-convex pattern for forming a micro concave-convex pattern on a resin film according to an embodiment of the present invention. First, the first method will be described with reference to FIGS. 1A-1G .
[0077] As shown in FIG. 1A , a liquid crystal drive element TFT and a wiring connection portion 31 are formed on the glass substrate 5 . A thin film of metal, insulator, or semiconductor is formed on the substrate 5 by cathode sputtering or CVD, and a resist is coated on it by a spin coating method, and baked at a high temperature to harden the resis...

Abstract
A method for manufacturing an optical element having a micro-concave-convex pattern that does not soften or deform in the process of forming the oriented film even if polyimide is used for the alignment film. Resin having a glass transition temperature exceeding 200° C. The film 4 is coated on the substrate 5, and the temperature of the resin film 4 is controlled so that it exceeds the glass transition temperature and is less than the thermal decomposition initiation temperature. pattern 40, after that, the temperature of the resin film 4 is cooled to a temperature lower than the glass transition temperature, and then the mold members (3A, 33) are separated.
Description
technical field [0001] The invention relates to an optical element provided with a resin film having a micro-concave-convex pattern, a method and a device for manufacturing a reflecting plate. Background technique [0002] In this specification, the micro-concave-convex pattern is a general term for one-dimensional or two-dimensional concavo-convex shapes with arbitrary widths, lengths, and shapes ranging from 0.1 μm to several 100 μm in the depth direction. In addition, the reflective liquid crystal display device is a general term for devices in which a liquid crystal material is sealed between a transparent counter substrate having a transparent electrode and an active matrix substrate having a reflective surface provided with a micro-concave-convex pattern. [0003] In recent years, applications of liquid crystal display devices in personal computers (PCs), televisions, word processors, video recorders, etc. have been continuously developed. On the other hand, in order ...
