Abstract

The present invention relates to a display device which is used for various types of electronic apparatuses, e.g., an electronic watch, an electronic pocket notebook, and the like, and an electronic device. In the device or apparatus, a solar battery member having a lot of light passing openings for passing light is provided between a liquid crystal display member and a plate-like light emitting member disposed at a position lower than that of the liquid crystal display member.

Claims

1. A display device comprising:

a plate-like light emitting member; and

a display plate disposed at a position higher than that of the light emitting member, the display plate having upper and lower surfaces;

wherein at least the upper surface of the display plate is made of metal, and the upper surface includes a narrow outgoing opening for emitting light from the light emitting member.

2. A display device as claimed in claim 1, wherein a decorated light-transmissive film member is disposed at a position higher than that of the display plate.

3. A display device as claimed in claim 1, wherein the narrow outgoing opening forms a design in the upper surface of the display plate.

4. A display device as claimed in claim 1, wherein a blinding wall is provided at a position corresponding to the narrow outgoing opening, inside the display plate.

5. A display device comprising:

a display plate having upper and lower surfaces in which at least the upper surface of the display plate is made of metal; and

a plate-like solar battery member disposed at a position lower than that of the display plate;

wherein a narrow incoming opening for introducing light downwardly is provided in the upper surface.

6. A display device comprising:

a plate-like light emitting member; and

a display plate disposed at a position higher than that of the light emitting member, the display plate having upper and lower surfaces;

wherein at least the upper surface of the display plate is made of metal, and the upper surface includes an opening for emitting light from the light emitting member.

7. A display device as claimed in claim 6, wherein a decorated light-transmissive film member is disposed at a position higher than that of the display plate.

8. A display device as claimed in claim 6, wherein the opening forms a design in the upper surface of the display plate.

9. A display device as claimed in claim 6, wherein a blinding wall is provided at a position corresponding to the opening inside the display plate.

10. A display device comprising:

a display plate having upper and lower surfaces in which at least the upper surface is made of metal; and

a plate-like solar battery member disposed at a position lower than that of the display plate;

wherein an opening for introducing light downwardly is provided in the upper surface of the display plate.
