Abstract: A display device includes a substrate, a pixel, an encapsulation layer, a pad electrode, and a circuit board. The substrate includes a display area and a pad area positioned outside the display area. The pixel is disposed on the display area. The encapsulation layer covers the pixel. The pad electrode is disposed on the pad area. A first surface of the pad electrode contains fluorine, overlaps a second surface of the pad electrode, and is positioned farther from the substrate than the second surface of the pad electrode is. The circuit board overlaps the pad electrode.

IPC: B41J2/165
Abstract: A head cleaning method includes contacting a nozzle surface of a head in which nozzle holes are defined with an absorbent on a pressurizer, starting a wiping operation at a first edge portion of the head closest to the pressurizer at a first position, and ending the wiping operation at a second edge portion of the head furthest away from the pressurizer at the first position, positioning the pressurizer at a second position to define a first angle between a first imaginary line parallel to a longitudinal direction of the head and a second imaginary line parallel to a longitudinal direction of the pressurizer, and starting the wiping operation at a third edge portion of the head closest to the pressurizer at the second position, and ending the wiping operation at a fourth edge portion of the head furthest away from the pressurizer at the second position.
