The present disclosure discloses a display apparatus, a stereoscopic display apparatus, and an application terminal thereof. The display apparatus includes a display panel and a light collimation module. The display panel includes an RGB pixel array. The RGB pixel array includes multiple RGB pixels disposed at intervals. The light collimation module includes a control electrode layer, a first transparent substrate, a liquid crystal layer, and a second transparent substrate. The control electrode layer is disposed within the intervals between the RGB pixels or at positions that are on the display panel and that are corresponding to the intervals between the RGB pixels. The first transparent substrate is disposed on the display panel and covers the control electrode. The liquid crystal layer is disposed on the first transparent substrate. The second transparent substrate is disposed on the liquid crystal layer.
