Abstract

The present disclosure provides a display panel for a display device including a touch electrode divided into first touch unit sensors having a first size and second touch unit sensors having a second size different from the first size. When a horizontal or vertical size of a second touch unit sensor is compared with a first touch unit sensor, the vertical size of the second touch unit sensor is smaller than that of the first touch unit sensor when the horizontal size of the second touch unit sensor is larger than that of the first touch unit sensor and the horizontal size of the second touch unit sensor is smaller than that of the first touch unit sensor when the vertical size of the second touch unit sensor is larger than that of the first touch unit sensor. Therefore, an area deviation of touch unit sensors forming a touch electrode is minimized and thus uniform and superior touch performance may be provided.
