A liquid crystal display device equipped with a built-in touch panel includes a second substrate on which a wiring pattern for configuring a touch panel is formed, and a flexible wiring substrate joined to the second substrate with an overlap portion, and electrically connected to the wiring pattern. The flexible wiring substrate is formed of a multilayer substrate having a first conductive pattern layer having a plurality of terminal portions electrically connected onto the wiring pattern, a second conductive pattern layer, an insulating layer interposed between the first conductive pattern layer and the second conductive pattern layer, and a plurality of contact portions that penetrates through the insulating layer, and electrically connects the plurality of terminal portions to the second conductive pattern layer. The plurality of contact portions is arranged to overlap with the plurality of terminal portions.
