Abstract: The present invention realizes a display device or input device having excellent ultraviolet protection property for the touch panel, display element or the like, while retaining optical characteristics, even when a small amount of or no optical film is used. The pressure-sensitive adhesive sheet of the present invention has a total light transmittance of 85% or more, a light transmittance at a wavelength of 380 nm of 5% or less, and a haze of 3% or less. The pressure-sensitive adhesive sheet preferably includes a pressure-sensitive adhesive layer containing an acrylic polymer and a triazine-based ultraviolet absorber.
