Abstract
Disclosed in the present disclosure are a display device and a display apparatus. The display device includes: a first substrate and a second substrate opposite to the first substrate, a light-emitting pixel array between the first substrate and the second substrate, a reflective plate at a backlight side of the light-emitting pixel array, and a polarization conversion structure and a polarization filtering structure which are successively arranged at a light emission side of the light-emitting pixel array; the polarization filtering structure is for filtering light emitted from the light-emitting pixel array side to the polarization filtering structure, so that target polarized light is transmitted, and non-target deflected light is reflected back; and the polarization conversion structure is for converting transmitted circularly polarized light into linearly polarized light, or converting transmitted linearly polarized light into circularly polarized light.
