Abstract: A display device including an input sensing unit. The input sensing unit includes sensors and signal lines connecting the sensors to a driving circuit for sensing a touch. The signal lines may include reception signal lines and transmission signal lines. A resistance value of the reception signal line connected to the sensor relatively far from the driving circuit is smaller than a resistance value of the reception signal line connected to the sensor relatively close to the driving circuit.

Abstract: A display apparatus including a display panel, an input sensor having an active area having a plurality of electrodes disposed therein and at least a portion of which overlaps the display area, and a non-active area which overlaps the non-display area. The active area has a central area and a peripheral area disposed outward from the central area. The plurality of electrodes include center electrodes which are disposed in the central area and peripheral electrodes which are disposed in the peripheral area and have a surface area less than that of the center electrodes. Each of the center electrodes includes a sensing pattern and a floating pattern, and each of the peripheral electrodes includes substantially only the sensing pattern. Thus, an embodiment of the inventive concept may provide the display apparatus that includes an input sensor having improved sensitivity in a peripheral area.
