Abstract: An inkjet printing head, includes: a chamber configured to store ink; a spray assembly, which is disposed under the chamber, and defines an ink transport path therein connected to an inner portion of the chamber, where ink that passes through the ink transport path is discharged to the outside through a bottom surface of the spray assembly; a first self-assembly monolayer covering the bottom surface of the spray assembly; an adhesive layer disposed between the bottom surface of the spray assembly and the first self-assembly monolayer and including a metal-carbon composition; and an inorganic material layer disposed between the adhesive layer and the first self-assembly monolayer.

Abstract: An organic light emitting diode display device includes a substrate, a driving transistor, a switching transistor, a first light absorbing layer, an organic insulating layer, and a sub-pixel structure. The substrate includes a first region and a second region. The driving transistor is disposed in the first region on the substrate. The switching transistor is disposed in the second region on the substrate, and includes a metal-oxide-based semiconductor. The first light absorbing layer is disposed on the driving and switching transistors. The organic insulating layer is disposed directly on the first light absorbing layer. The sub-pixel structure is disposed on the organic insulating layer.
