Abstract: The reliability of a display device with an input device is improved. A plurality of detection electrodes (input position detection electrodes) forming an electrostatic capacity between them and a common electrode of a display device to detect an input position are formed on a different substrate from substrates configuring the display device. Moreover, a polarizing plate and the substrate on which the plurality of detection electrodes are formed are adhesively fixed via, for example, an adhesive layer so that the plurality of detection electrodes are fixed so as to be separated apart from the display device. Thus, a distance between electrodes (the detection electrode and a driving electrode) for detecting an input position can be set separately from a thickness of the display device, and therefore, reduction in detection sensitivity (detection reliability) for the input position due to increase in the electrostatic capacity can be suppressed.

Abstract translation: 提高了具有输入装置的显示装置的可靠性。 在与构成显示装置的基板不同的基板上形成有多个检测电极（输入位置检测电极）与显示装置的公共电极之间形成检测输入位置的静电电容。 此外，通过例如粘合剂层将偏振片及其上形成有多个检测电极的基板粘合固定，使得多个检测电极被固定成与显示装置分离。 因此，用于检测输入位置的电极（检测电极和驱动电极）之间的距离可以与显示装置的厚度分开设置，因此由于增加而导致输入位置的检测灵敏度（检测可靠性）降低 在静电容量方面可以抑制。
