Definitions
- the present invention relates to a dispersion composition, and more particularly to a dispersion composition that can be suitably used for a film having high reflection performance.
- the brightness of the liquid crystal display can be increased without sacrificing the viewing angle or color reproducibility by selectively reflecting and recycling the backlight light.
- a brightness enhancement film is used. Improving the brightness requires less power to illuminate the display, thus reducing power consumption and reducing the heat load on the electronic components, thus extending the life of the electronic components. Is also possible. Therefore, various proposals for the structure of the brightness enhancement film have been made. For example, trying to improve the brightness of a liquid crystal display by enclosing a large number of fine bubbles in the resin film constituting the brightness enhancement film, and by multiple reflection (high refractive index) at the interface between the gas phase and the solid phase in the resin film. The structure to be known is known.
- fine particles that can be used industrially include titanium oxide particles, barium titanate particles, and zirconium oxide particles.
- titanium oxide particles when titanium oxide is blended with an organic compound such as a resin, the deterioration of the resin may be promoted, so that its use is limited.
- barium titanate may adversely affect the environment. Therefore, it is preferable to use zirconium oxide.
