Definitions

  • the optical sheet 20 and the display surface 11a of the image source 11 are separated from each other by a predetermined dimension.
  • the present invention is not limited to this, and the optical sheet 20 and the display surface 11a of the image source 11 are separated.
  • An intermediate layer is provided between the display surface 11a of the image source 11 and the surface on the viewer side of the optical sheet 20, and reaches at least the viewer's eyes E1 and E2 of the image light V.
  • the air layer may not be present in the region where the light to be transmitted (the light visually recognized by the observer) is transmitted.
  • the optical sheet 40 of the second embodiment includes the third optical layer 43 on the observer side ( ⁇ Y side) of the second optical layer 22, and the unit shape 42 a includes the second optical layer 42, the third optical layer 43, and the like.
  • This is different from the optical sheet 20 of the first embodiment in that it is formed at the interface 402. Therefore, in the following description of the second embodiment and the third and fourth embodiments to be described later, parts having the same functions as those of the first embodiment described above are denoted by the same reference numerals or the same reference numerals at the end. Thus, overlapping description will be omitted as appropriate.

Abstract

L'invention concerne un dispositif d'affichage avec lequel il est possible d'empêcher une région de non-image d'être reconnue visuellement en raison d'une région de non-pixel présente entre des régions de pixel d'une source d'image. Le dispositif d'affichage (1) comprend : une source d'image (11) dans laquelle une pluralité de pixels sont disposés en réseau et qui projette une lumière d'image; une lentille (12) qui agrandit la lumière d'image (V) et projette celle-ci vers un observateur; et une feuille optique (20) qui est disposée entre la source d'image (11) et la lentille (12), ou est disposée sur le côté observateur de la lentille (12). La feuille optique (20) comprend, sur son intérieur ou sa surface, au moins une surface de forme optique dans laquelle une forme d'unité convexe ou concave s'étendant le long de la surface de feuille est disposée dans une direction orthogonale à la direction d'extension.
