  • Patent number: 8915604
    Abstract: A prism sheet includes a base film having one flat surface and an optical refractive section having a plurality of prisms arranged along a first direction to constitute first and second prism parts. The optical refractive section is integrally formed with another surface of the base film that is opposite to the flat surface of the base film, and each of the prisms has a predetermined cross-sectional shape. The first prism part includes a first prism of the plurality of prisms, which first prism has a constant height along a second direction that intersects the first direction. The second prism part includes a second prism of the plurality of prisms, which second prism has a variable height in the second direction, and a maximum value of the variable height of the second prism is higher than the constant height of the first prism.
