OPTICAL SHEET AND DISPLAY

摘要

An optical sheet capable of enhancing contrast is provided. The optical sheet includes a layer configured to control light incident on the layer and then allow the light to exit towards the observer side. The optical sheet includes: an optical functional sheet layer (12) having multiple prisms (13, 13, . . . ) capable of transmitting light and multiple light-absorbing parts (14, 14, . . . ) capable of absorbing light, the multiple prisms and multiple light-absorbing parts being arranged alternately along a sheet plane of the optical sheet; and an electromagnetic-wave shield layer (12). The electromagnetic-wave shield layer (12) is positioned on a side opposite to the observer side relative to the optical functional sheet layer.
