Title: (EN) DISPLAY DEVICE AND ELECTRONIC APPARATUS
Abstract: front page image
(EN)

A display device includes a display section (11) having a first display surface and a second display surface (S1, S2) facing each other. The display section (11) includes a first display panel (111) disposed on the first display surface (S1) side, and including a plurality of light emitting elements, and a second display panel (112) disposed on the second display surface (S2) side, and including a plurality of light control elements each performing light control for control of transmission or reflection of incident light performing reflective image display utilizing the reflection of the incident light.
