Description

Display panel and display device including the same The present specification relates to a display device, and more specifically, to a display panel capable of improving image defects by improving the electrostatic discharge path and a display device including the same. With the advent of the information age, the field of display devices that visually display electrical information signals is developing rapidly, and research is continuing to improve the performance of various display devices, such as miniaturization, lightweighting, and low power consumption. Representative display devices include Liquid Crystal Display Devices (LCDs) and Organic Light Emitting Display Devices (OLEDs). Organic light-emitting displays are self-emissive displays that, unlike liquid crystal displays, do not require a separate light source, allowing for the manufacturing of lightweight and thin forms. Furthermore, organic light-emitting displays are not only advantageous in terms of power consumption due to low-voltage driving, but also offer excellent color reproduction, response speed, viewing angle, and contrast ratio, making them promising for use in various fields. FIG. 1 is a plan view of a display panel according to a first embodiment and a display device including the same. Figure 2 is a cross-sectional view along the line I-I' of Figure 1. Figure 3 is a cross-sectional view showing an open defect along the line I-I' of Figure 1. FIG. 4 is a plan view of a display panel according to a second embodiment and a display device including the same. Figure 5 is a cross-sectional view along the line I-I' of Figure 4. FIG. 6 shows an extension wiring according to the first example in the extension area (EA) of FIG. 4. Figure 7 shows the extension wiring according to the second example in the extension area (EA) of Figure 4. FIG. 8 shows an extension wiring according to the third example in the extension area (EA) of FIG. 4. FIG. 9 shows the extension wiring according to the fourth example in the extension area (EA) of FIG. 4. FIG. 10 is a plan view of a display panel according to a third embodiment and a display device including the same. FIG. 11 is a plan view of a display panel according to a fourth embodiment and a display device including the same. The advantages and features of this specification and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, this specification is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of this specification is complete and to fully inform those skilled in the art of the scope of the invention, and this specification is defined only by the scope of the claims. Shapes, sizes, ratios, angles, numbers, etc. disclosed in the drawings for explaining the embodiments of this specification are exemplary and are not limited to the depicted items.
