A display apparatus and a visual displaying method for simulating a holographic 3D scene are provided. The display apparatus comprises: a display screen; two front-facing 3D cameras, being configured to capture human-eye 3D position information; a 3D human-eye tracking algorithm processing unit, being configured to generate a first signal and a second signal according to the human-eye 3D position information; a 3D scene generating unit, being configured to receive the first signal, render and acquire the corresponding left visual-channel 3D scene and the corresponding right visual-channel 3D scene according to the first signal; and an electronic grating, being configured to receive the second signal and adjust the working angle according to the second signal so that the left visual-channel 3D scene is incident into the left eye of the user and the right visual-channel 3D scene is incident into the right eye of the user. Thereby, the display apparatus and the visual displaying method for simulating a holographic 3D scene according to the present disclosure allow to see different 3D images at different view angles just as in the real world, thus achieving holographic displaying of an object or scene.
