Display apparatus

Abstract

A display device includes a transparent display panel and a dimming panel disposed behind the transparent display panel. The dimming panel includes a first substrate, a first transparent electrode, a first light-shielding electrode, a first insulating layer, a second substrate, a second transparent electrode, a second light-shielding electrode, a second insulating layer, and an electrophoretic display medium layer. The first transparent electrode and the first light-shielding electrode are disposed on the first substrate. The first insulating layer is disposed between the first transparent electrode and the first light-shielding electrode. The second transparent electrode and the second light-shielding electrode are disposed on the second substrate. The second insulating layer is disposed between the second transparent electrode and the second light-shielding electrode. The electrophoretic display medium layer is disposed between the first light-shielding electrode and the second light-shielding electrode, and between the first transparent electrode and the second transparent electrode.
