A display device includes a display panel, a transparent plate and at least one compressible transparent member. The display panel has a display surface. The transparent plate is disposed on the display panel and has a light incident surface and a first light emitting surface opposite to each other. The display surface and the light incident surface face each other, and the transparent plate has at least one side surface connected between the light incident surface and the first light emitting surface. The compressible transparent member is disposed on the side surface and has a second light emitting surface, and the second light emitting surface is tilted relative to the first light emitting surface. Moreover, a display apparatus including a plurality of the display devices is also provided. When the display devices are spliced to form the display apparatus, the problem of visible black lines of splicing seams is mitigated.
