Abstract:
1. A liquid crystal display device, comprising: a liquid crystal display panel which has a pair of polarizing plates; and a first light diffusing layer which has a first major surface and a second major surface opposing each other and which is arranged such that the first major surface opposes a viewer side surface of the liquid crystal display panel, wherein the first light diffusing layer includes a first region formed of a first substance which has a first refractive index N the plurality of second regions are arranged in the first region at a predetermined pitch P in one direction in a plane parallel to the second major surface, each of the plurality of second regions forms a plurality of interfaces with the first region, the interfaces being inclined by α° from a normal of the second major surface, and θ where Lb is a typical viewing distance of the liquid crystal display panel, and a is expressed as follows: in which Lt is a distance from the second major surface to a liquid crystal layer side surface of a viewer side substrate of the liquid crystal display panel, and θ′ is expressed as follows:
