Abstract
Provided is a light diffusion film laminate for a reflective display device which is capable of reducing the change in the brightness of the image without reducing the visibility not only from a predetermined observation position (for example, the front direction of the screen), but also from a slightly inclined direction from the predetermined observation position (for example, the front direction of the screen), thereby having excellent display characteristics, and a reflective display device including the light diffusion film laminate.
