PROBLEM TO BE SOLVED: To provide a liquid crystal display that suppresses the generation of scratches on a surface of a polarization plate when a touch operation is performed where a gesture operation rubbing the surface of the polarization plate frequently occurs, and can achieve good display.SOLUTION: A liquid crystal display 100 comprises an in-cell type or on-cell type touch panel sensor 1f of a projection type capacitance system, and further a display device 1 having a first polarization plate 1a arranged on a display surface and a protective layer 6 arranged on the first polarization plate 1a. The protective layer 6 has a pencil hardness of 4H or more.SELECTED DRAWING: Figure 4 【課題】偏光板の表面を擦るジェスチャ操作が頻発するタッチ操作を行う場合に偏光板の表面に対するキズの発生を抑制し、良好な表示を実現できる液晶表示装置を提供することを目的とする。【解決手段】液晶表示装置１００は、インセル型またはオンセル型の投影型静電容量方式のタッチパネルセンサー１ｆを備え、かつ、表示面に第１の偏光板１ａが配置された表示素子１と、第１の偏光板１ａ上に配置された保護層６とを備えている。保護層６の鉛筆硬度は４Ｈ以上である。【選択図】図４
