PROBLEM TO BE SOLVED: To achieve both a reduction in thickness and manufacturing cost in a display device with a position input device having a capacitive position input device built therein.SOLUTION: A display device 100 comprises a display device body 4, a polarization optical element 5, and a capacitive position input device 1. The position input device 1 is arranged between the display device body 4 and polarization optical element 5. The position input device 1 includes a transparent heat-resistant material layer 2 formed of a transparent heat-resistance material and a sensor part 3 that is arranged on one surface of the transparent heat-resistant material layer 2. The transparent heat-resistant material layer 2 has a thickness in a range from 0.5 to 50 μm.SELECTED DRAWING: Figure 1 【課題】静電容量方式の位置入力装置が組み込まれた位置入力装置付き表示装置において、薄型化と製造コストの低減を両立させる。【解決手段】表示装置１００は、表示装置本体４と、偏光光学素子５と、静電容量方式の位置入力装置１を備えている。位置入力装置１は、表示装置本体４と偏光光学素子５の間に配置されている。位置入力装置１は、透明耐熱性材料よりなる透明耐熱性材料層２と、透明耐熱性材料層２の一方の面上に配置されたセンサ部３を有している。透明耐熱性材料層２は、０．５〜５０μｍの範囲内の厚みを有している。【選択図】図１
