Abstract
A liquid crystal display device is provided in which a touch panel and a liquid crystal display panel are placed under a front window. A touch-panel flexible wiring substrate is connected to the touch panel, and a main flexible wiring substrate is connected to the liquid crystal display panel. The main flexible wiring substrate includes a touch-panel control IC and a touch-panel electronic component group to control the touch panel. The touch-panel flexible wiring substrate includes only lines. In this configuration, there is only one flexible wiring substrate, or the main flexible wiring substrate, on which the electronic components are mounted. As a result, the production cost of the liquid crystal display device as a whole can be reduced.
