Abstract:
An optical film comprising a layer consisting mainly of an organic compound and a layer containing inorganic fine particles wherein a content of the organic compound having a molecular weight of 1000 or less is 30% by mass or less based on a content of the inorganic fine particles. The optical film exhibits a low haze and a high contrast when being assembled into a liquid crystal display device.
