Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent yellowing around the periphery caused by a distorted counter substrate of a liquid crystal display panel in a liquid crystal display device in which a liquid crystal display panel and a front window are bonded to a touch panel by an ultraviolet-curable resin, the front window having a black-frame print around its periphery.SOLUTION: An ultraviolet-curable resin is formed over a touch panel, and a liquid crystal display panel is bonded to the touch panel. Subsequently, the ultraviolet-curable resin is formed over the touch panel, and a front window is bonded to the touch panel. While the ultraviolet-curable resin is cured unevenly because of a black-frame print formed around the periphery of the front window, the touch panel and a counter substrate of the liquid crystal display panel are already bonded together at this time. This prevents the uneven cure of the ultraviolet-curable resin from distorting the counter substrate alone. As a result, it is possible to avoid unevenness of the gap between the counter substrate and a TFT substrate of the liquid crystal display panel and a resulting yellowing phenomenon around the periphery.
