Abstract

The present invention provides a display device including a transflective display panel, a backlight module disposed, and a light-adjusting panel disposed between the transflective display panel and the backlight module. The transflective display panel includes a first substrate, a second substrate, a first circuit layer disposed on the first substrate, a plurality of reflective electrodes disposed on the first circuit layer, a first color filter layer including a plurality of color filters and disposed on the second substrate, and a first liquid crystal layer disposed between the color filters and the reflective electrodes. Each of the reflective electrodes includes an opening, and each of the color filters corresponds to one of the reflective electrodes. The light-adjusting panel includes a third substrate, a fourth substrate, a second circuit layer disposed on the third substrate, and a second liquid crystal layer disposed between the second circuit layer and the fourth substrate.
