Abstract:
An image display apparatus that that can easily separate an image display apparatus from a touch panel. The image display apparatus comprises a liquid crystal panel (image display apparatus main body), a touch panel that has a fine, uneven structure on its surface and faces the liquid crystal panel via a gap, and an adhesive member for securing these, the adhesive member comprising a substrate, a first adhesive layer, and a second adhesive layer, wherein an adhesive strength (W1) between the first adhesive layer and the liquid crystal panel is less than an adhesive strength (W3) of the first adhesive layer and the substrate, an adhesive strength (W3′) of the second adhesive layer and the substrate, and an adhesive strength (W5) of the second adhesive layer and the touch panel, and wherein a breaking strength (W4) of the substrate is greater than W3′ and/or W5.
