PROBLEM TO BE SOLVED: To provide an input display device capable of reducing occurrence of a display defect and occurrence of malfunction without losing a natural operational feel.SOLUTION: An input display device 1 includes a liquid crystal layer 2 containing liquid crystal molecules that are homogeneously aligned in the absence of an electric field, a polarizer 3 disposed on the viewing side of the liquid crystal layer 2, a capacitance sensor 4 disposed between the polarizer 3 and the liquid crystal layer 2, and an antistatic layer 5 disposed between the polarizer 3 and the capacitance sensor and attached to the polarizer 3. The capacitance sensor 4 has a transparent substrate 6, a transparent electrode pattern 7 formed on the transparent substrate, and an adhesive layer 8 formed on the transparent substrate to embed the transparent electrode pattern. The antistatic layer 5 has a surface resistance value per unit area of 1.0×10to 1.0×10 /sq.
