Abstract: A touch sensor includes a substrate, sensing electrodes (SEs), and sensing lines (SLs). The substrate includes a sensing area (SA) and a peripheral area outside the SA. The SEs overlap the SA. The SLs overlap the peripheral area, are respectively connected to the SEs, and include first SLs (FSLs) alternatingly arranged with second SLs (SSLs). Each of the SLs includes: a first metal layer (FML) on the substrate; a first insulating layer (FIL) on the FML and including a first contact hole (FCH) exposing the FML; and a second metal layer (SML) on the FIL and connected to the FML through the FCH. A width of the FML of each of the FSLs is different from a width of the FML of each of the SSLs. A width of the SML of each of the FSLs is different from a width of the SML of each of the SSLs.

Abstract: A display device may include a plurality of pixels. Each of the plurality of pixels may include a plurality of stages electrically connected in series. Each of the plurality of stages may include a plurality of light emitting elements. A storage component may store location information of a defective pixel having a defect in the plurality of stages. A compensation component may generate compensated data by compensating for a grayscale value in image data of a normal pixel based on a first degradation coefficient, and by compensating for a grayscale value of the defective pixel corresponding to the location information based on a second degradation coefficient different from the first degradation coefficient, and thus generate compensated data. A data driver may generate data voltages based on the compensated data, and provide the data voltages to the plurality of pixels.
