ABSTRACT:
The present invention provides an optical functional sheet and a display device that are capable of keeping a given degree or more of front luminance and are capable of substantially reducing brightness nonuniformity. To this end, the optical functional sheet has a base3, and prisms4arranged in a lattice pattern on at least one surface3aof the base3, wherein each of the prisms4has two bottoms L1parallel to a first direction D1, two first inclined surfaces S1that are inclined so as to face each other, two bottoms L2parallel to a second direction D2that is substantially perpendicular to the first direction D1, and two second inclined surfaces S2that are inclined so as to face each other, and the area Ss2of one of the second inclined surfaces S2to the sum S2s1of the areas of the two first inclined surfaces S1, or the area Ss1of one of the first inclined surfaces S1to the sum S2s2of the areas of the two second inclined surfaces S2is more than 0.5 times to 2.5 times or less.
