| titleOfInvention | Image display apparatus and optical member therefor |
| abstract | The present invention relates to an image display apparatus capable of switching a display mode between a directional display mode of displaying a first image in a first viewing direction and a second image in a second viewing direction and a non-directional display mode of displaying the same image in both the first and second viewing directions, the image display apparatus comprising an image forming unit that forms an image and emits image light representing the image; and an optical member disposed adjacent to an emitting side of the image forming unit and used for switching the display mode, the optical member including two light-transmitting plate members; at least one lens member disposed between the two plate members, the lens member having a predetermined refractive index; a refractive-index variable medium sealed in a gap between the lens member and the two plate members; and a refractive-index adjusting unit that adjusts a refractive index of the refractive-index variable medium, wherein the refractive-index adjusting unit is configured to: (i) set the optical member to be in a first usage state in which the optical member performs a lens action by adjusting the refractive-index variable medium to have a refractive index different from the predetermined refractive index so that the display mode of the image display apparatus is set to be the directional display mode; and (ii) set the optical member to be in a second usage state in which the optical member functions as a light-transmitting plate performing no lens action by adjusting the refractive-index variable medium to have the same refractive index as the predetermined refractive index so that the display mode of the image display apparatus is set to be the non-directional display mode. |
