Abstract: Provided is a near-eye display apparatus, comprising: a first display (11), used for displaying a first image, entering a beam splitter (30) by means of a first imaging lens (12); a second display (21), used for displaying a second image, entering the beam splitter (30) by means of a second imaging lens (22), the beam splitter (30) being used for transmitting the imaging light beam of the first imaging lens (12) and reflecting the imaging light beam of the second imaging lens (22); a waveguide plate (40), located on the light exit path of the beam splitter (30), and used for receiving outgoing light from the beam splitter (30) and transmitting same; the waveguide plate (40) is internally provided with a light-taking component (400), the light-taking component (400) being used for reflecting the imaging light beam transmitted in the waveguide plate (40) toward a position where a human eye is located. The image distances of the first imaging lens (12) and the second imaging lens (22) are different, thus it is possible to display the first image and the second image on two image planes, and, by means of adjusting the human eye, when observing an image of an image plane the image of the other image plane is blurry, which is consistent with a sensation of viewing an actual scene, thus eliminating vergence-accommodation conflict.
