Abstract: A viewing angle limiting apparatus and a display apparatus are provided. The apparatus comprises a first optical member having a plurality of lower light shielding members, and a second optical member having a plurality of upper light shielding members and facing the first optical member. Each of the plurality of upper light shielding members may be spaced apart from each of the plurality of lower light shielding members in a thickness direction of the first optical member and disposed to be alternate with each of the plurality of lower shielding members. Therefore, since a length of each of the lower light shielding members and the upper light shielding members may be formed to be short, the light shielding members may be manufactured more easily than the case that one light shielding member is provided longitudinally up and down, and a defect rate may be lowered, whereby productivity may be enhanced.
