  • 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.
