Abstract

A novel display device that is highly convenient or reliable. The display device includes a first display element, a second display element, a color film, and a reflective electrode. The first display element includes a first pixel electrode and a liquid crystal layer. The second display element includes a second pixel electrode and a light-emitting layer. The first pixel electrode is electrically connected to the reflective electrode. The reflective electrode includes an opening through which light emitted from the light-emitting layer passes. The color film faces the reflective electrode with the liquid crystal layer placed therebetween.

Claims (50)

1. A display device comprising:

a first display element;

a second display element;

a color film; and

a reflective electrode,

wherein the first display element comprises a first pixel electrode and a liquid crystal layer,
