Abstract
In an image display apparatus, a protruding portion is fixed to a chassis on a back side Z2 of a planar member and protrudes towards the planar member. The protruding portion has one or more first protruding members and one or more second protruding members and defines a small allowance region and a large allowance region for the planar member. In the small allowance region, an amount of displacement of the planar member towards the chassis side is regulated at most to a first predetermined value by the one or more first protruding members. In the large allowance region, an amount of displacement of the planar member towards the chassis side is regulated at most to a second predetermined value larger than the first predetermined value by the one or more second protruding member.
