PROBLEM TO BE SOLVED: To provide an optical sheet capable of preventing deterioration of dyes for absorbing near infrared light or a neon line, and to provide a video display device provided with the optical sheet.SOLUTION: In the optical sheet for controlling light emitted from a plasma display panel and emitting the light to an observer side, having a plurality of layers and including at least an optically functional sheet layer having prism parts formed to be arranged in parallel along a sheet surface so as to be light-transmissible on a base material layer and light-absorbing parts arranged in parallel between the prism parts so as to be light-absorbable, the prism part is formed by curing a prism constitution composition including a radiation curing prepolymer, a multifunctional acrylate monomer and a polymerization initiator and the prism constitution composition contains ≥50 mass% multifunctional acrylate monomer, based on the total amount of the prism constitution composition. The video display device includes the optical sheet. |
