TOUCH PANEL DEVICE AND METHOD FOR MANUFACTURING THE SAME, AND DISPLAY DEVICE |
摘要 |
A touch panel device includes a plurality of touch position detection electrodes provided in a touch area, and a detection circuit configured to detect a touch position or positions based on a capacitance or capacitances formed between the touch position detection electrodes and a touching object. The touch position detection electrodes include a first electrode and second electrodes formed along a curved substrate surface. The first electrode has a center portion provided at a center of the touch area, and a plurality of tip portions radially extending from the center portion to reach a periphery of the touch area. The second electrodes are located in a region including the periphery of the touch area, and one of the second electrodes is located between each adjacent pair of the tip portions.
