Description

Display device and electronic device having the same Various embodiments of the present disclosure relate to a display device and an electronic device including the same. With the development of multimedia, interest in display devices is increasing. For example, there is growing interest in display devices such as Liquid Crystal Displays (LCDs) and Organic Light Emitting Displays (OLEDs). The above display device may generally include a display panel and a driving element (e.g., Display Driver Integrated-circuit: DDI) that controls the driving of the display panel. The display panel may include a display area and a non-display area (or DS (Dead space) area). The display area may include a plurality of pixels, and the non-display area may include power wiring and ground wiring that supply power to drive the pixels. Meanwhile, the power wiring and ground wiring may be arranged (or formed) in a structure where at least a portion overlaps. Due to this overlapping structure, a short circuit may occur between the power wiring and ground wiring. Furthermore, when the power wiring and ground wiring are short-circuited, damage to the wiring caused by the short circuit may spread due to the low resistance of the power wiring and ground wiring. Therefore, recently, there is a demand for a method to prevent short circuits between the power wiring and ground wiring.

According to one embodiment, the substrate (200) can be formed of a flexible material. For example, the substrate (200) can be a film-type flexible printed circuit board (FPCB). The substrate (200) can be bonded to the display panel (100) in a film-on-glass (FOG) or film-on-board (FOB) manner. The above substrate (200) may include a driving element (250) that controls the driving of a display panel (100) (e.g., light emission of a pixel (P)). The driving element (250) may receive various power signals and driving signals (e.g., initialization signal, scan signal, data signal, compensation signal, etc.) that control the driving of the display panel (100) from an external device (e.g., the main board (not shown) of the electronic device (40) of FIG. 4), and supply the received power signals and driving signals to the display panel (100). The driving element (250) may include a Display Driver Integrated Circuit (DDI). The driving element (250) may be coupled to the substrate (200) in a chip-on-film (COF) manner. For example, the driving element (250) may be coupled to the central part of the substrate (200), though it is not limited thereto. The display panel (100) can output (e.g., display) various images (e.g., still images or video). The display panel (100) can be formed from various materials. For example, the display panel (100) can be formed from inorganic mater
