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.
