Abstract
A display apparatus includes a backlight source, a privacy filter disposed on the backlight source, a light adjusting panel disposed on the privacy filter, and a display panel disposed on the light adjusting panel. The light adjusting panel includes a first substrate, a first electrode, a second electrode, a first vertical alignment film disposed on the first substrate, a second substrate disposed opposite to the first substrate, a second vertical alignment film disposed on the second substrate, and a positive liquid crystal layer disposed between the first vertical alignment film and the second vertical alignment film. The first electrode and the second electrode are disposed on the first substrate. Here, the first electrode has a plurality of first slits, and a plurality of orthogonal projections of the first slits on the first substrate overlap an orthogonal projection of the second electrode on the first substrate.
