Abstract

A display apparatus, frame member, and reflection suppressing member that are capable of achieving an improvement in display quality and an improvement in visibility, are provided. In a case, a reflection suppressing portion that attenuates emitted display light is formed on an annular wall portion (frame portion). The reflection suppressing portion previously suppresses undesirable display (display that is directed to a not-intended direction) which can occur due to the display light emitted from an outer periphery of a display face being reflected by the case and the like.

Claims

1. A display apparatus comprising:

a display unit for displaying individual images in a plurality of viewing directions on a common screen;

a frame portion through which an opening is formed that exposes the common screen for viewing through the opening, the frame portion provided near at least one edge portion of the display unit; and

a reflection suppressing portion provided in at least one part of the frame portion at a periphery of the opening, the reflection suppressing portion suppressing an image that should he outputted to one viewing direction from being reflected to another viewing direction at the frame portion.

2. The display apparatus of claim 1, wherein the reflection suppressing portion includes a light-attenuation portion that attenuates display light emitted from the display unit.

3. The display apparatus of claim 1, wherein the reflection suppressing portion includes a reflection angle modification portion that reflects an image that should be outputted in the one direction in a direction other than the other viewing direction.

4. The display apparatus of claim 1, wherein the reflection suppressing portion includes a reflectance reduction portion that reduces the reflectance of display light emitted from the display unit.

5. The display apparatus of claim 1, wherein the reflection suppressing portion includes a reflection prevention portion that causes cancellation of display light emitted from the display unit by using light interference.

6. The display apparatus of claim 1, wherein the reflection suppressing portion includes a light source that diffusely reflects display light emitted from a vicinity of an edge portion of the display unit.

7. The display apparatus of claim 1, wherein the reflection suppressing portion is configured by applying a delustering agent that reduces reflection of display light emitted from the display unit.

8. The display apparatus of claim 1, wherein the frame portion is configured installable to or removable from the display unit.

9. The display apparatus of claim 1, wherein the reflection suppressing portion that suppresses an image that should be outputted in one viewing direction, from being reflected to another viewing direction at the frame portion, is configured installable to or removable from at least one part of the frame portion.

10. A frame member provided near at least one edge portion of a display unit for displaying individual images in a plurality of viewing directions on a common screen,

wherein the frame member is configured installable to or removable from the display unit,

an opening is formed through the frame member that exposes the common screen for viewing the opening, and

the frame member is provided, in at least one part at a periphery of the opening, with a reflection suppressing portion that suppresses an image that should he outputted to one viewing direct ion from being reflected to another viewing direction at the frame member.

11. A reflection suppressing member provided in at least one part of a frame portion provided near at least one edge portion of a display unit for displaying individual images in a plurality of viewing directions on a common screen,

wherein an opening is formed through the frame portion that exposes the common screen for viewing,through the opening, the reflection suppressing member is configured installable to or removable from the frame portion at a periphery of the opening, and the reflection suppressing member suppresses an image that should be outputted in one viewing direction, from being reflected to another viewing direction at the frame portion.
