发明名称 Reflecting plate, reflection type liquid crystal display device and processes for manufacturing same
摘要 An object of the present invention is to provide a reflecting plate having excellent reflecting characteristics and a reflection type liquid crystal display apparatus having an improved display quality. A mask has a plurality of basic uneven spot patterns for individual pixels, and two or more uneven regions for at least one basic uneven spot pattern are formed. Any two of the two or more uneven regions appear at least in a relation of parallel displacement in which the uneven spot patterns are displaced in parallel with each other, among relations of parallel displacement, rotational displacement and reversal of uneven spot pattern, and the uneven regions are irregularly arranged. A reflecting plate and a reflection type liquid crystal display apparatus both having convexes are manufactured by an exposure of a photosensitive resin film using the mask. Even in the case where an exposure step is repeated in different positions, no seam is observed. Accordingly, even in the case of a high parallelism of an incident light, an interference color can be prevented to improve the reflecting characteristics and the display characteristics.
