Abstract:
A dual prism sheet includes a base film, upper prisms formed on an upper surface of the base film and lower prisms formed on a lower surface of the base film. A cross-section of the upper and lower prisms is formed as an isosceles triangular shape having a base and a vertex angle, and a phase of the upper prisms is delayed between about 0 and about 0.5 times of a prism pitch with respect to a phase of the lower prisms.
