Abstract

A display apparatus is provided with a frame 20 that is mounted to the head portion of an observer 10, and an image display device 20 which is attached to the frame 20, an image display device 30 is provided with an image forming device 40, an optical system 50 that guides an image from the image forming device 40 to a pupil of an observer, and a support member 60₁ that supports the image forming device 40. When a direction of the support member 60₁ that corresponds to a first direction of an image is set as an X direction, and a direction of the support member 60₁ that corresponds to a second direction of the image, which is different from the first direction, is set as a Y direction, a support surface 61 of the support member 60 that supports the image forming device 40 is curved along the X direction and/or the Y direction, and therefore, the image forming device 40 is curved.

Claims

1. A display apparatus comprising:

(i) a frame; and

(ii) an image display device which is attached to the frame,

wherein the image display device includes

(A) an image forming device,

(B) an optical system that guides an image from the image forming device to a pupil of an observer, and

(C) a support member that supports the image forming device,

wherein, when a direction of the support member that corresponds to a first direction of an image is set as an X direction, and a direction of the support member that corresponds to a second direction of the image, which is different from the first direction, is set as a Y direction, a support surface of the support member that supports the image forming device is curved along the X direction, the Y direction or the X direction and the Y direction, and therefore, the image forming device is curved.

2. The display apparatus according to claim 1,

wherein a degree of curvature along the X direction of the support surface of the support member is greater than the degree of curvature along the Y direction.

3. The display apparatus according to claim 1,

wherein the support member includes a holding member,

wherein an external shape of the image forming device is a rectangular shape, and

wherein an outer peripheral portion of the image forming device that extends along the X direction is fixed to the support member using the holding member.

4. The display apparatus according to claim 1,

wherein an external shape of the image forming device is a rectangular shape, and

wherein an outer peripheral portion of the image forming device that extends along the X direction is interposed by the support member.

5. The display apparatus according to claim 1,

wherein an external shape of the image forming device is a rectangular shape, and

wherein wiring from an outer peripheral portion of the image forming device, which extends along the Y direction, extends to an external outside.

6. The display apparatus according to claim 1,

wherein the optical system is formed from a reflecting mirror that reflects an image from the image forming device and a lens group into which an image that is reflected by the reflecting mirror, is input.

7. The display apparatus according to claim 6,

wherein the lens group is disposed between a pupil of an observer and the reflecting mirror, and

wherein the image forming device is disposed above the reflecting mirror.

8. The display apparatus according to claim 7,

wherein the lens group is formed to have one group and 3 lenses,

wherein a second lens has a negative power, and

wherein a refractive index of a material that configures the second lens is greater than a refractive index of a material that configures a first lens and a third lens.

9. The display apparatus according to claim 8,

wherein the first lens and the third lens have a positive power.

10. The display apparatus according to claim 1,

wherein the display apparatus includes an image display device for a left eye and an image display device for a right eye.

11. The display apparatus according to claim 10,

wherein the display apparatus further includes an image display device inter-distance adjustment device that adjusts a distance between the image display device for the left eye and the image display device for the right eye.

12. The display apparatus according to claim 1,

wherein the image display device is formed from an organic electroluminescence display device.

13. The display apparatus according to claim 1,

wherein the frame is mounted on a head portion of an observer.

14. An image display device comprising:

(A) an image forming device;

(B) an optical system that guides an image from the image forming device to a pupil of an observer; and

(C) a support member that supports the image forming device,

wherein, when a direction of the support member that corresponds to a first direction of an image is set as an X direction, and a direction of the support member that corresponds to a second direction of the image, which is different from the first direction, is set as a Y direction, a support surface of the support member that supports the image forming device is curved along the X direction, the Y direction or the X direction and the Y direction, and therefore, the image forming device is curved.
