A display apparatus is provided. The display apparatus includes a supporting member having a containment structure configured to contain a two-dimensional (2D) display terminal for displaying a parallax image. The display apparatus also includes a transflective device configured to face a display surface of the 2D display terminal and to transmit and reflect light from the displayed parallax image. Further, the display apparatus includes a connecting mechanism configured to connect the supporting member with the transflective device, wherein the containment structure includes an installation part configured to install a light-splitting device; an area of the light-splitting device is greater than or equal to an area of the display surface; and a three-dimensional (3D) image to be viewed is formed after the light from the parallax image displayed by the 2D display terminal is separated by the light-splitting device and transmitted and reflected by the transflective device.
