Abstract:
The objective of the present invention is to provide a display device with excellent display quality, which has a light emitting pattern that is reduced in light blurring. A display device according to the present invention is sequentially provided at least with a transparent substrate, a first layer containing a light scattering body, a second layer that contains a light scattering body at a content ratio lower than that of the first layer, a light blocking layer having an opening pattern, and a light source that emits light in an area equal to or larger than the area of the opening pattern, in this order. This display device is characterized in that the content ratio of the light scattering body in the first layer is within the range of 30-90% by volume, and the thickness of the first layer is within the range of 3-15 μm.
