Abstract

A display apparatus and a touch display apparatus are disclosed, particularly, a display panel with functions including displaying and mirror reflection is disclosed. The display apparatus comprises display panel, a reflecting film disposed above the display panel, wherein the reflecting film has a first penetrating axes, wherein a display light is emitted from the display panel in a light-emitting direction, when an ambient light irradiates onto the display panel in a direction that different from the light-emitting direction, the ambient light with a polarization direction that different from the first transmission axes is reflected by the reflecting film.

Claims
