Optical stack and liquid crystal display apparatus

An optical stack comprising:

• a light scattering film converting light received at a light receiving surface into scattering light therein and then outputting the scattering light outside from a light output surface, and
• a sheet provided on the light output surface side of the light scattering film, wherein
• the light scattering film comprises:
• a functional layer formed of a light-transmissive composition including an organic polymer compound and light scattering particles,
• wherein the functional layer includes a first surface receiving the light and a second surface from which the scattering light is output,
• wherein the light scattering particles have an average particle size of 1.5 μm or larger, and
• wherein the functional layer includes a particle layer formed of light scattering particles having a content of 60% by volume or higher among the light scattering particles, the particle layer expanding along the first surface and being concentrated in a direction perpendicular to the first surface.
