发明名称 DISPLAY DEVICE
摘要 A display device having a highly reliable electrostatic capacitive type touch panel which allows finger touch inputting and possesses excellent detection sensitivity is provided. With respect to X electrodes and Y electrodes which are formed on an electrostatic capacitive type touch panel, either one of the X electrodes and the Y electrodes is divided corresponding to a ratio between the number of X electrodes and the number of Y electrodes, and a floating electrode is formed in gaps formed along with the reduction of area of the electrode thus adjusting the area of the electrode. Due to the contraction of the area of the individual electrode, a noise level can be lowered more compared to lowering of a signal level and hence, an S/N ratio can be increased thus enhancing the detection sensitivity. Further, a line is branched on a flexible printed circuit board, intersecting lines are formed on a back surface of the flexible printed circuit board, and the intersecting lines are arranged to orthogonally intersect with lines formed on a front surface of the flexible printed circuit board thus lowering line capacitance.
