Naked eye type and glasses type switchable stereoscopic display device

A naked eye type and glasses type switchable stereoscopic display device includes a display panel and a switching module. The display panel is used to provide first display information and second display information. The switching module is disposed on a side of a display surface of the display panel. The switching module forms a plurality of lenses to change directions of the first display information and the second display information under a naked eye type stereoscopic display mode, and the switching module provides a first phase retardation mode and a second phase retardation mode under a glasses type stereoscopic display mode. The first phase retardation mode corresponds to the first display information and renders the first display information a first polarization state, and the second phase retardation mode corresponds to the second display information and renders the second display information a second polarization state.
