Abstract
An image display device includes a display panel, a plurality of light emitting elements, a reflective sheet, and a first optical sheet. The display panel displays an image on a front face of the display panel. The light emitting elements are disposed along one edge of the display panel. The reflective sheet is disposed opposite a rear face of the display panel. The reflective sheet reflects light from the light emitting elements toward the rear face of the display panel. The first optical sheet is disposed between the display panel and the reflective sheet. The first optical sheet has a plurality of protrusions on a face of the first optical sheet that is opposite the reflective sheet. The protrusions have ridgelines extending along a direction that is different from a direction in which the one edge of the display panel extends.

An image display device comprising:
- a display panel that displays an image on a front face of the display panel;
- a plurality of light emitting elements disposed along one edge of the display panel;
- a reflective sheet disposed opposite a rear face of the display panel, the reflective sheet reflecting light from the light emitting elements toward the rear face of the display panel;
- and
- a first optical sheet disposed between the display panel and the reflective sheet, the first optical sheet having a plurality of protrusions on a face of the first optical sheet that is opposite the reflective sheet,
- the protrusions having ridgelines extending along a direction that is different from a direction in which the one edge of the display panel extends,
- the protrusions including
- a plurality of first protrusions having a plurality of first ridgelines, respectively, the first ridgelines being parallel to each other and extending along a first direction that is different from the direction in which the one edge of the display panel extends, and
- a plurality of second protrusions having a plurality of second ridgelines, respectively, the second ridgelines being parallel to each other and extending along a second direction that is different from the first direction and the direction in which the one edge of the display panel extends the first direction being perpendicular to the second direction.
