A display apparatus having a backlight module, a modulatable parallax barrier module, a polarizer film and a display panel is provided. The backlight module provides a linear polarized light having a first polarization direction. The modulatable parallax barrier module has an alignment state and a transparent state, and has a first alignment film with a first alignment direction on the light-emitting side. The linear polarized light passing through the modulatable parallax barrier module in the transparent state is kept in the first polarization direction, and passing through the modulatable parallax barrier module in the alignment state is transformed to a second polarization direction. The polarizer film has a transmission axis inclined toward either the first polarization direction or the second polarization direction. The modulatable parallax barrier module selects one of the alignment state and the transparent state according to an image information provided by the display panel. |
