Abstract

To provide a goggle type display device system that can prevent harm to user'"'"'s health. If anomaly is recognized in mind and body of a user, first video signals provided from an external device stop being displayed on LCD panels and, instead, outside scenery taken by CCD image capture elements is displayed. The user may be alarmed by this about anomaly of his or her body and, further, relaxed by looking at the outside scenery presented.

Claims

1. A display system comprising:

a frame; and

a display device attached to the frame and arranged to be placed in front of an eye of a user of the display system,

wherein the display device comprises a pixel which comprises;

a transistor;

a first insulating film over the transistor;

a pixel electrode over the first insulating film; and

a second insulating film over the first insulating film, the second insulating film covering an edge portion of the pixel electrode, and

wherein a portion of the second insulating film, which overlaps with the edge portion, has a taper shape.

2. The display system according to claim 1,

wherein the display device is an electroluminescence display device.

5. The display system according to claim 1,

wherein the display device is configured to display an image supplied from an external device.

6. The display system according to claim 1, further comprising:

an image capture element configured to capture a scenery outside the display system,

wherein the display device is configured to display the scenery captured by the image capture element.

7. The display system according to claim 6,

wherein the image capture element is attached to the frame.

8. The display system according to claim 5, further comprising:

an image capture element configured to capture a scenery outside the display system;

an image sensor configured to obtain a vital information of the user; and

a video signal control circuit configured to determine which of the image supplied from the external device or the scenery captured by the image capture element is displayed on the display device.

3. A display system comprising:

a frame; and

a display device attached to the frame and arranged to be placed in front of an eye of a user of the display system,

wherein the display device comprises a pixel which comprises;

a transistor;

a covering material over the filling material, and

wherein a portion of the second insulating film, which overlaps with the edge portion, has a taper shape.

4. The display system according to claim 3,

wherein the display device is an electroluminescence display device.

9. The display system according to claim 3,

wherein the display device is configured to display an image supplied from an external device.

10. The display system according to claim 3, further comprising:

an image capture element configured to capture a scenery outside the display system,

wherein the display device is configured to display the scenery captured by the image capture element.

11. The display system according to claim 10,

wherein the image capture element is attached to the frame.

12. The display system according to claim 9, further comprising:

an image capture element configured to capture a scenery outside the display system;

an image sensor configured to obtain a vital information of the user; and

a video signal control circuit configured to determine which of the image supplied from the external device or the scenery captured by the image capture element is displayed on the display device.

13. The display system according to claim 3, further comprising a passivation film between the electrode and the filling material.

14. The display system according to claim 3, further comprising a desiccant in the filling material.
