Abstract

A compact and lightweight display device having an image pickup function and a two-way communication system which can shoot an image of a user as an object and display an image at the same time without degrading image quality by disposing a semi-transmitting mirror or the like which blocks an image on the display screen (display plane). The display device having the image pickup function includes a display panel capable of transmitting visible light at least and arranging display elements which can be controlled by voltage or current, and an image pickup device disposed around the display panel. The image pickup device is input with data of an image of a user or the like by a reflector, or equipped with a fiberscope bundling optical fibers.

Claims

1. A display device comprising:

a display panel comprising;

a first substrate,

a first transparent electrode formed over the first substrate,

a light emitting layer formed over the first transparent electrode,

a second transparent electrode formed over the light emitting layer, and

a second substrate over the second transparent electrode;

a reflector provided over the first substrate or the second substrate; and

an image pickup device provided at an edge of the display panel,

wherein the image pickup device shoots an image of an object transmitted in the first substrate and the second substrate.

2. A display device according to claim 1, wherein the reflector comprises a plurality of reflecting surfaces.

3. A display device according to claim 1, wherein the reflector reflects an image of an object transmitted in the first substrate and the second substrate.

4. A display device according to claim 1, wherein the first substrate and the second substrate are transparent.

5. A display device according to claim 1, wherein the light emitting layer comprises an electroluminescence material.

6. A display device according to claim 1, wherein the display panel is a see-through type.
