PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of preventing mixing of impurities into a liquid crystal material from a sealing material layer, and a method for manufacturing the liquid crystal display device.SOLUTION: The liquid crystal display device includes: an array substrate and a counter substrate disposed opposing to each other and bonded by a frame-like sealing material layer; a liquid crystal layer disposed in a region enclosed by the sealing material layer; and a frame-like non-display region defining a display region inside. The sealing material layer comprises a cured product of an acrylic resin and/or an epoxy resin containing particles that absorb visible rays and/or infrared rays to generate heat and a thermal polymerization initiator. The surface of the counter substrate opposing to the array substrate comprises a first region corresponding to the display region, a second region extending from an outer edge of the first region to an inner edge of the sealing material layer, a third region extending from an outer edge of the second region halfway toward an outer edge of the sealing material layer, and a fourth region extending from an outer edge of the third region to an outer edge of the sealing material layer. At least in the third region, a light selective transmissive layer that blocks visible rays and transmits infrared rays is disposed.SELECTED DRAWING: Figure 2 【課題】シール材層から液晶材料への不純物の混入を防ぎ得る液晶表示装置、及びその製造方法を提供する。【解決手段】対向配置され、枠状のシール材層で貼り合わされたアレイ基板及び対向基板と、シール材層によって囲まれた領域内に配置された液晶層と、内側に表示領域を規定する枠状の非表示領域とを備え、シール材層は、可視光線及び／又は赤外線を吸収して発熱する粒子及び熱重合開始剤を含有するアクリル樹脂及び／又はエポキシ樹脂の硬化物を含み、対向基板のアレイ基板と対向する面は、表示領域に対応する第１領域と、第１領域の外縁からシール材層の内縁まで延在する第２領域と、第２領域の外縁からシール材層の外縁に向かって途中まで延在する第３領域と、第３領域の外縁からシール材層の外縁まで延在する第４領域を含み、少なくとも第３領域には、可視光線を遮断して赤外線を透過する光選択透過層が配置されていることを特徴とする液晶表示装置。【選択図】図２
