Description

Electronic apparatus The present invention relates to an electronic device capable of displaying an image and detecting an external input. Electronic devices are activated according to electrical signals. Electronic devices may include electronic components composed of various electronic elements, such as a display unit that displays images or a sensing unit that detects external inputs. Electronic elements may be electrically connected to each other by variously arranged signal lines. Electronic components can be electrically connected to external circuits through pads. As the integration density of electronic components increases and the number of signal lines grows, the area required to accommodate these signal lines may increase. Furthermore, as the number of signal lines increases, a fine patterning process is required to form signal lines of minute size.
