Abstract

A display device includes a first region and a second region adjacent to the first region. A display element included in the first region has a function of reflecting visible light and a function of emitting visible light. A display element included in the second region has a function of emitting visible light. In an electronic device including the display device, the first region is located on a first surface (e.g., top surface) on which a main image is displayed, and the second region is located on a second surface (e.g., side surface) on which an auxiliary image is displayed.

First claim

The invention claimed is:

1. An electronic device comprising:
a display panel including display regions in both end portions of a first direction of the display panel,
wherein the display regions in both end portions of the first direction of the display panel each comprise a protruded portion extending in a second direction of the display panel, the second direction being perpendicular to the first direction,
wherein a width of the protruded portion in the first direction is smaller than a width of one of the display regions in the first direction, and
wherein the display panel comprises an EL element.

2. The electronic device according to claim 1 , wherein the second direction is a longitudinal direction of the display panel.

3. The electronic device according to claim 1 , wherein the display regions are bendable in the first direction.

4. The electronic device according to claim 1 , further comprising a housing,
wherein the housing comprises side surfaces facing each other,
wherein the display regions are over the side surfaces of the housing, and
wherein the display regions each include a curved surface.
