Abstract
There is disclosed a liquid crystal display device in which a touch panel and a front window are attached to a front surface of a liquid crystal display panel with a touch-panel flexible wiring substrate mounted to the touch panel. The front window is attached to the touch panel by an adhesive sheet. The touch panel and the front window may be peeled off in the vicinity of the portion in which the touch-panel flexible wiring substrate is mounted to the touch panel, due to mechanical shock. In order to prevent the peeling-off of the touch panel and the front window, protrusions are formed in the adhesive sheet to increase the adhesive force between the touch panel and the front window in this portion.
