Abstract
A display panel displays an image through pixels of a display area. A touch driving circuit detects a touch through a touch sensing unit of the display panel and generates touch coordinate data therefrom. A display driving circuit supplies a data voltage to the pixels of the display area and controls an image display timing of the pixels. A circuit board includes touch lines, ground lines, interface lines, power lines, and option control lines and is electrically in contact with the display panel. A low-resistance film covers an upper surface of the circuit board. The low-resistance film is disposed on an upper surface of the interface lines and corresponds to the interface lines.
