ILLUMINATION DEVICE, DISPLAY DEVICE, AND TELEVISION RECEIVING DEVICE

摘要

A liquid crystal display device (10) is provided with: an LED (24); a rectangular optical sheet (18) for imparting an optical action to light from the LED (24); a rectangular liquid crystal panel (11) disposed so as to be layered on the optical sheet (18); and a frame (15) constituting a frame shape, disposed so as to enclose the optical sheet (18), and sandwiching both edges on the long side of the optical sheet (18) between the liquid crystal panel (11) and itself while selectively pressing portions of the optical sheet (18) that are closer toward the center than the two end sides of the edges. Because the two edges on the long side of the optical sheet (18) are selectively sandwiched to hold the optical sheet (18) in place, displacement of the optical sheet (18) can be prevented or minimized. A deflection occurring in the optical sheet (18) can be relieved in a portion of the optical sheet (18) which is not sandwiched nor held in place, i.e., the portions on the two end sides of the edges.

主权项

1. An illumination device, comprising:
a light source; an optical sheet having a rectangular shape and imparting an optical effect on light from the light source; a display component having a rectangular shape and being provided on the optical sheet; and a frame member having a frame shape surrounding the optical sheet and, on at least one edge of the optical sheet, selectively and directly or indirectly pressing an area that is located relatively more towards a center of said edge of the optical sheet than both sides of said edge so as to secure said area to the display component.
