AI Technical Summary
Technical Problem
The increase in size of touch panel-integrated display devices leads to increased load on drive and detection electrodes, causing potential waveform collapse and inaccurate touch detection.
Method used
A touch panel-integrated display device configuration with a counter electrode, drive electrode, detection electrode, and intermediate electrode in the same layer, where the intermediate electrode separates and reduces the load on the drive and detection electrodes, and facilitates easy identification of short circuits.
Benefits of technology
The reduced load on electrodes allows for larger display devices with improved touch detection accuracy and ease of short circuit repair.

Abstract
The present invention provides a touch panel-integrated display device that reduces the load on the drive electrodes and detection electrodes, thereby enabling a larger touch panel-integrated display device. [Solution] The display device comprises a pixel electrode, a counter electrode 12c, a drive electrode 12a, a detection electrode 12b, and an intermediate electrode 12d. The counter electrode 12c is positioned opposite the pixel electrode. The detection electrode 12b forms a capacitance with the drive electrode 12a. The intermediate electrode 12d is formed in the same layer as the counter electrode 12c, the drive electrode 12a, and the detection electrode 12b. The intermediate electrode 12d is positioned between two of the electrodes: the counter electrode 12c, the drive electrode 12a, and the detection electrode 12b.
