Abstract:
An optical sheet used as a component for a touch panel or a display element of a display device is capable of imparting a variety of characteristics such as anti-glare properties and preventing the scintillation of image light in ultrahigh-definition display elements having a pixel density of 300 ppi or more. The optical sheet has an uneven shape on a surface, and the uneven shape satisfies at least one of three disclosed conditions relating to the inclination angles of the uneven portions of the sheet and the distribution curves of the inclination angles.
