Beschreibung
Zusammenfassung:	The present invention relates to a prism layer (10) superimposed on the front surface of a display (20), in which: a plurality of prism parts (11) are vertically arranged; the prism parts (11) each have an upper slope surface (12) and a lower slope surface (13), and have a corner part (14) which has a forward protruding triangular shape in a cross-sectional view; the angle θ1 of the upper slope surface (12) with respect to a rear surface (15) is set to 60° to 120°, and the angle θ2 of the lower slope surface (13) with respect to the rear surface (15) is set to 5° to 45°; and the pitch Pp of a groove part (16) between the prism parts (11) is made smaller than the vertical pitch Pd of a pixel (21) of the display (20).
