MANUFACTURING METHOD OF DIFFUSED REFLECTING PLATE FOR REFLECTIVE LIQUID CRYSTAL DISPLAY AND PHOTOSENSITIVE ELEMENT FOR FORMING DIFFUSED REFLECTIVE GROUND LAYER FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a diffused reflecting plate for a reflective liquid crystal display with satisfactory yield by excellent shape maintainability of an uneven surface by which light can be diffused and reflected under high temperature and excellent adhesiveness of a substrate of a diffused reflective ground layer under high temperature and humidity in the diffused reflective ground layer and a photosensitive element for forming the diffused reflective ground layer to be used for the method.;SOLUTION: The manufacturing method of the reflecting plate for the reflective liquid crystal display is characterized by forming the diffused reflective ground layer by (I) a process for laminating a photosensitive element for forming the diffused reflective ground layer constituted by laminating a photosensitive resin composite layer on the uneven shaped surface of a tentative supporting body having the uneven shaped surface on a substrate, (II) a process for irradiating active beams on the photosensitive resin composite layer as an image, (III) a process for separating and removing the tentative supporting body having the uneven shaped surface, (IV) a process for forming a pattern by selectively removing the photosensitive resin composite layer by development, (V) a process for irradiating the active beams on the photosensitive resin composite layer on which the pattern is formed and (VI) a process for heating the photosensitive resin composite layer on which the pattern is formed and further forming a reflective film on the diffused reflective ground layer.;COPYRIGHT: (C)2003,JPO
