Description of the Invention (1) [Technical Field to which the Invention belongs] The present invention relates to a film-forming composition for a light-diffusing reflection plate used for a liquid crystal display element and the like A light diffusion reflection plate having a film formed of the composition, and a liquid crystal display element having the light diffusion reflection plate. [Previous Technology] Since liquid crystal displays require surface illumination with uniform and high front luminance, those who have a backlight unit have been the mainstream in the past. However, due to the popularity of portable terminals in recent years, the number of transflective and reflective liquid crystal displays has increased greatly from the viewpoint of power saving. The transflective and reflective liquid crystal display is provided with a reflective plate such as an aluminum plate under the liquid crystal panel, and obtains luminance by reflecting light from the upper portion of the panel. However, when this method is used, because the reflecting plate is a flat surface, when the incident direction of incident light from the upper part of the panel is inclined, the direction of the reflected light deviates from the front direction of the panel, and sufficient front luminance cannot be obtained. In order to improve the above-mentioned disadvantages of the transflective and reflective liquid crystal displays, a technique using a so-called light diffusion plate has been disclosed. In this method, a fine uneven shape is added to the surface of the reflector to diffuse the direction of the reflected light, so that a front luminance can be obtained. For example, Japanese Patent Application Laid-Open No. 2000- 1 1 8 86 discloses a technique of forming a metal film on a surface of a glass substrate roughened by chemical uranium etching, and providing a concave-convex shape on the surface of a reflecting plate. According to this method, not only the complicated steps are required to protect the inner surface of the glass substrate from the etching solution, but also because of the use of corrosive etching solution, the Chinese national standard (CNS) A4 specification (2) is used on the device and the paper size. ! 0X297mm) TaI " (Please read the notes on the back before filling out this page) 576851 A7 B7 V. Description of the invention (2) There are cost problems in the process. (Please read the precautions on the back before filling in this page.) Also, Japanese Patent Application Laid-Open No. 2000-193807 discloses that a solution-like composition containing a hydrolyzate of a fluorine compound and an alkoxysilane is coated on a substrate. A technique of forming a film having a concave-convex shape by using phase separation when forming a coating film, and forming a metal film thereon. This method is difficult to control the uneven shape and it is difficult to efficiently obtain diffused light. Moreover, not only the adhesion to the substrate is deteriorated, but the transparency is also insufficient. Therefore, it cannot be used as a transflective liquid crystal display element. The present invention has been made in view of the above circumstances, and an object thereof is to provide a liquid-crystal display element having a rough surface for light diffusion and reflection, excellent adhesion to a substrate, heat resistance, and transparency, and easily forming a reflective or semi-transmissive liquid crystal display element.
