Abstract

A display device includes a first display panel, a second display panel, a quantum dot layer and a backlight module. The first display panel includes a first substrate, a second substrate, and a first display medium layer disposed between the second substrate and the first substrate. The second display panel includes a third substrate, a fourth substrate and a second display medium layer disposed between the third substrate and the fourth substrate. The quantum dot layer is disposed between the second substrate and the fourth substrate, and the quantum dot layer has multiple first quantum dot particles, multiple second quantum dot particles and multiple diffusing particles dispersed therein. The backlight module is located at a side of the second display panel.
