Abrégé
(EN)

An anti-peeping display panel and an anti-peeping display apparatus are disclosed. The anti-peeping display panel includes: a plurality of pixel units, each of the pixel units including a plurality of sub-pixels; a color filter layer including a plurality of color filter units in one-to-one correspondence with the plurality of sub-pixels, each of the color filter units being configured to filter light emitted by a corresponding sub-pixel; and a black matrix layer including a plurality of black matrices, each of the black matrices being located in an area adjoining adjacent color filter units, the black matrix being configured to block at least part of light emitted by a sub-pixel adjacent to the black matrix, and an included angle between an emission direction of the at least portion of light and a normal of a light emergent surface of the sub-pixel being greater than or equal to 40°.
