Abstract
Optical sheets can be fixed easily and positively in a liquid-crystal display device having a liquid-crystal display panel in which a liquid-crystal layer sandwiched between a pair of substrates and a lighting unit provided on a surface opposite to a display surface of the liquid-crystal display panel. For this purpose, a projection is provided on a sidewall of an accommodator, and the projection is inserted into a hole provided in optical sheets arranged within the accommodator, thereby fixing the optical sheets in the accommodator. The length along a certain straight line of a top plan form of a tip of the projection is longer than the length along the certain straight line of the hole formed in the optical sheets, thus preventing the optical sheets from falling out of the accommodator.
